Don't, about the mk 2 but eurooptic has a used repr with 4 position gas block that runs well suppressed. I should know since it was mine and the round count is 180. Accuracy was solid 1 moa.
I just picked one up last Friday. I am still waiting for a few more various brands of match ammo I ordered to come in before I break it in and test said ammo for the rifles preference and ability. It's supposed to be guaranteed sub minute accuracy and I certainly hope it is for the amount of coin I dropped on it. It is the R.E.P.R MkII 20" barrel in FDE. I will be trying the following rounds to see what it likes.
Fedaral Gold Medal Match - 168 and 175gr.
Hornady Match - 168 and 175gr.
Hornady Black - 168gr.
Black Hills Match - 168 and 175gr.
Nosler Match Grade - 168 and 175gr.
Sellier & Bellot Match - 168gr.
I will post the results on here after I get a chance to make it out to the range.

I will be running a Nightforce NXS 3.5-15x50 on Larue mount (not shown in picture) @ 100 yards during testing and I am going to talk to a buddy of mine about borrowing his sand bags just for good measure.
Not yet still collecting various brands and grain match ammo. I am trying to track down 20 rounds of Lake City M118lr. It will probably be late Dec. to early Jan. before I will complete my performance write up. I read all the other reviews online for this rifle and wasn't very pleased with their range reviews they only showed one or two groups and most only tried two or three types of ammo (most of the time within the same brand), which is why I am have decided to do my own review. I am looking to have 15 different types of match ammo of at least 8 or 9 different brands. and will be showing be showing the best and worst out of each boxes 5 shot groups as well as the groups shot during the barrel break in (which will be done with 60-80 rounds of Federal xm80c). The rest of the ammo used will be 168gr-185gr bullet weight. If you or any one you know could spare 20 rounds of the Lake city M118lr it would be much appreciated. All I can find is in bulk and I don't want to buy 500 rounds if its not the ammo my rifle is going to prefer.
Sorry been a long time since I've seen LC M118lr in 20 rounds for sale ...good luck look forward to your results ... but did see this you might be interested in .....http://www.sgammo.com/product/imi/2...5-grain-bthp-smk-otm-razorcore-match-ammo-imi
Thanks for the link I just ordered the IMI 168 and 175 match as well as the Privi P. 168 match. I will try to list the current boxes of ammo that I will be testing today or tomorrow when I get off work.
Awesome ... i was thinking the 175 rdf and the 168 eld m would be almost perfect ballistics for ur combo ..

I believe this should be enough to get an unbiased result of what the rifle is truly capable of. After spending this kind of money (I think it will be fair to say that) I will not be very pleased if it doesn't preform per their sub-minute accuracy "guarantee". I will chrono 5 rounds of each box at the time of testing and post their ranges. I will be shooting off sand bags at 100 yards targets. I am currently reviewing different optics and mounts at this time haven't settled on which one exactly yet but all are top quality scopes (Schmidt Bender, Us Optics, Steiner, or Nightforce).
Also I am still trying to track down 20 rounds of Lake City M118LR if any one has them to spare for the test, it would be very much appreciated.
I will try to keep an update on status

I stopped by the range on Saturday and started the barrel break in. I only had enough time to shot the first 20 rds. with cleaning after each shot. I was using the Nightforce NXS 3.5-15x50, sighted in in three shots but so far the groups were pretty terrible averaging about 3"s at 100 yrds shooting Federal xm80c. I need to send more time at the range Thursday and try adjusting the gas block (casings were coming out at about 5 o'clock. Using the same bags setup I also was shooting 5 shot groups with a friends Stiller tactical 30 in 308 with hand loads between the shots I was putting threw my repr and I held .370"-.550" groups over 5 groups with his rifle (as did he)... Which didn't make me feel all that happy with the repr since I could put the shots all threw the same hole with the Stiller and then go to my repr and watch rounds be scattered inconsistently. I will also have to check to make sure nothing is wrong with optic/mount. I know the ammo I am shooting is surplus but I have a RRA ar-15 with a 20" barrel that holds sub-minute accuracy shooting steel cased Wolf FMJ. So the repr should be able to preform similarly being 4x the price you think. I will do some more tinkering with it and post more information and the photos as I get more time to shoot it.
Don't get discouraged after all is done im sure you will be more then happy / jmo but putting anything other then match ammo i would think is a wast of time ... if you want to step it up get some GMM 308 175 and test and adjust the gas setting from what i understand this is the ammo the gun was built around ... good luck and keep us posted ... https://www.americanrifleman.org/articles/2016/12/30/lwrci-repr-mkii-rifle-review/ http://dailycaller.com/2017/06/13/gun-test-lwrcs-repr-mkii/
I have the REPR mk2 in 308. Working on my 168 and 175 handloads. With 168 SMK and AMax I get a bit under 1 MOA. During breaki-in and immediately after cleaning it opens up a lot. Still playing with powders on the 175s. Only been shooting at 100 yds.
Interested in thoughts and accuracy of this rifle as well
The REPR's seem to be really hit or miss and n my experience. My SWAT team picked up 4 for our snipers and 3 of the 4 had significant problems with both accuracy as well as function issues with a TBAC Ultra 7 attached. Sent them back 3 times to LWRC and each time the returned with new parts / updated parts and the same issues. Finally we sent them all back for a refund and purchased something else.
i loved the ergos of the REPR but not the problems we had with the platform. I had considered picking on up for a personal rifle but decided to go with a JP LRP-07 instead.

Is this the original repr or the new model? From what I've read they are not in the same class.
Bump. Anyone else with one? No real reviews out there. Am interested in picking one up.
Sorry it's been a while since I've updated any information. I was finally able to spend a lot of time at the range putting another several hundred rounds of various match ammo threw the rifle as well as many hours behind the rifle. I haven't been updating because I wanted to make sure I gave the rifle a fair chance to prove itself. My rifle (REPR MkII 20") is a 1.25-1.5 MOA rifle about 50% of the time, It's only had 2 groups so far that where sub-moa. The accuracy isn't even the worse problem I've had so far. To reiterate what I've stated before I am shooting off sand bags front and rear using a Nightforce NXS 3.5-15x50 (at x15) mounted with a Larue 20MOA STOMP mount at 100 yards and at every shooting session I have brought an additional 2-3 other rifles to confirm that it's the rifle and not just me having a "bad day" at the range. I will shot one or two of the other rifles after a few groups with the REPR. Two of the rifles are custom bolt guns built off Stiller actions and constantly shoot 1/4MOA, The other is a RRA with a 20" full float chrome lined hbar barrel which shoots a consistent 1-1.5MOA (it will shoot sub-MOA once every 5 to 10 groups) with Wolf steel cased ammo. The REPR is very picky about magazines I have two steel 5rd mags for a sr25 that the REPR hates with a vengeance, with metal mags it will feed maybe 10% of the time (I'm talking about inserting the mag and dropping the bolt, not cycling issue that is a whole other issue) and usually took 2-5 tries before it would strip the round or send the bcg all the way into battery (if ever). With pmags the rifle fed pretty consistently only 10 or so times did it fail to strip a round or fail to go into battery. The REPR also hates Hornady match and supermatch ammo. I had to resort to feeding the rounds into the chamber one at a time (no magazine in the rifle just sticking the rounds in the chamber by hand and drop the bolt) and still had problems with failure to go into battery and failure to fire do to light primer strikes. So far 4 rounds of Hornady match 175gr. BTHP will not fire/fully go into battery at all after dozens of attempts of hand loading them into the chamber and dropping the bolt from charging handle all the way to the rear and it still wouldn't go into battery or fire the rounds(light primer strikes). The failure to chamber rounds were a common problem threw out all ammo brands, some where worse than others (Federal Gold Medal Match being the least problematic). I will say the adjustable gas block did help with the cycling and accuracy of the rifle when it would actually feed rounds from a magazine. At most settings the rifle groups about 2-4MOA but after adjusting the gas block and finding the sweet spot for that particular round it would come down to about 1.5MOA. I have contacted LWRC about my issues and am waiting for them to email me my shipping Label to send it back to them to work on. I have also heard of several other folks having similar experiences with there rifles and hopefully LWRC will get it squared away. I am not all that impressed right now with the REPR MkII, I purchased this rifle to have an accurate and reliable piston rifle so far it has proven itself to be either of these. If I had known before I bought the rifle what I now know I would have just went with the HK MR762A1. The main reason I bought the REPR was because of the 20" barrel that I wanted for longer range shooting. But if the rifle wont even function properly with match grade/handload ammo it's not any good for anyone... I honestly hope LWRC will be able to help me but, we will see.

I have a REPR MkII 20" FDE - Read details above
A friend of mine has a REPR I guess it would be considered a MkI with a 16" barrel his is just as and sometimes more accurate than mine and has been very reliable with few if any issues at all over the last 10 years. I have handled his on a couple of occasions and was impressed with it, which is why I gave the REPR MkII a chance. Now I wishing I hadn't though.
Save your money and wait and see if LWRC gets these rifles squared away or I would suggest HK MR762A1 if you want piston rifle or Larue OBR if your cool with DI guns.
WOW ,,, very upsetting ... i had high expectations for mk 2 after the csass testing ..You would think it shoots and functions for a 4k rifle.... LWRC would say it shoots this with this factory load lot # ... i will hang on to my $$$ till lwrc makes it right or proves it works and shoots under moa ... good luck thanks for the info ...please keep us updated on customer service and results
I just received my shipping label today and will take off my glass and send the rifle probably tomorrow or Thursday. I found another guy with almost identical problems and he sent it in and it returned with the same problems in which he sent it in to get fixed. And they just told him to keep sending it back to them until they get all the bugs worked out of it but, instead he just sold the rifle and bought something else. I really hope they will get mine fixed. I hate having spent +$4000 on a rifle, +$1000 on various brands and weight of match ammo, and several vacation days off work just to end up with a rifle that has to repeatedly get sent back to the factory for not functioning or shooting as they claim there rifles are capable of... and for the money spent it should be preforming as they advertise if not better. But we will see.
If anyone else owning one of these also has or has had similar issues I would like to know.
Also I found out that at there factory there range is only 50 yards they use ball surplus for function checks and FGMM 168gr BTHP (no lot# for the ammo, but it would be nice to know) for accuracy. No sure how they can guarantee sub-MOA by only shooting 50 yards with 1 or 2 shots, but who knows. We will see... And hopefully they will get mine all fixed up working properly and turned into a "tack driver"(their words) so I can come back on here and give you all a good honest and accurate review on the rifle and it's abilities.

What hand loads are you guys using?
Well I sent the rifle in last night so we will see how it goes. While I was getting my rifle ready to ship back in for rework, I gave the rifle one last thorough inspection. While examining the feed ramps and rear of the chamber I noticed that there was evidence that the right side feed ramp was guiding the rounds about .050"-.100" below the radii that the rifle has around the chamber itself. There is a copper dot about .050"-.100" below the chamber on the right feed ramps side that you can see on the rear of the barrel with drag marks leading into the chamber where as the left side rounds the copper marks were only present on the radii leading into the chamber. This stood out to me because there were times when the rifle failed to go into battery after a couple attempts of dropping the bolt on the round and the round would act as if it was being blocked or in a bind and I would have to use my finger a pull the round back into the magazine then drop the mag and then remove the round from the magazine in order for me to be able to clear the round from the rifle. With the rounds hitting the rear of the barrel every other round and crushing or bending the tip of the rounds it would also explain the accuracy issues I have been having. Unfortunately the feed ramps are machined into the barrel extension and the only way to bring the right side ramp up so that it is aligned with the chamber would be to replace the barrel extension itself with one who's feed ramps have proper alignment with the chamber. I would greatly appreciate it if they could check this out and see if it does in fact solve the feeding issues. Not that it would help with the failure to fire issues, but you know, one less thing...

Came across this little review and video ..thought i would share
...https://www.ammoland.com/2017/05/lw...ything-want-rifle-nothing-dont/#axzz55JErIZRp
Just get a Larue or JP.
I'm seeing similar accuracy issues as the OP. I can't get this rifle to shoot less than 1.5 MOA with any load, recipe, or factory ammo.
but with the proof research you loose the barrel life longevity ( current barrels are warrantied for 20,000 rounds), also there is no proof that the new barrel will make any improvement on accuracy since they have yet to prove the sub-MOA accuracy guarantee of their current barrels. The only benefit would be weight reduction but this would also throw off the weight of the rifle to the rear. It would be better if they just made and sold us the rifles as they were advertised.
I've recently purchased a CSASS, which is basically the same thing.
Zero'd it at the range the other week with some factory Hornadys. It floated at about 3/4ish moa with 3 round groups on an atlas upfront with a sandbag on the back.
Pretty comparable with my LMT.
If you're gonna be suppressing it, it's probably one of the better semis.
It's got a 20 position adjustable piston system for you to really tune it to your suppressor. I've never ran mine suppressed though.

Were they the 168gr or 178gr / Match or supermatch Hornady. Just asking because mine had a few issues with the 168's and it wouldn't cycle 178's at all. it would just jam up or fail to go into battery. And neither would do better than 2.5MOA
Also is yours a 16" or 20"

16" with 168gr out of a 20rd m3 pmag. I've never tried 178 out of it.
Bummer to hear that it's tossing rounds like that. If I recall, LWRC promises atleast 1 moa.
Was customer service any help?
If my LGS has the ammo, sure I'd be willing to check it out for you.
I'm curious myself.
I have a new MK 2 with 40 rounds Federal Sierra Match Kings to sight in my day scope and night optics. Perfect operation. Everything was great at the range, shooting mostly MOA groups, which is my ability. Last night, I was out hunting. Load my first PMAG Gen 3, 10 round loaded with plastic tipped Hornady Black 168 gr. I go to charge and the round jams 1/2 way into the chamber against the left side of the feed ramp. I could not dig the round out with my fingers. Walk back to the truck. Grab a butter knife to pry the round out. Unsuccessful. Push the mag ejection button while pulling and jiggling the mag as hard as I could. Finally, the mag comes out along with the round, while almost dropping my gun and my $8000 thermal scope. Throw mag back into the truck, grab another loaded mag, entire situation repeats four more times until I can no longer pull out the mag. Grab flat head screw driver, to pry out the round, PMAG drops on the ground, dropping two rounds with it. Pull charging handle back 4-5 times while pointing rifle down to make sure that the gun is unloaded. Point rifle upwards to check if a round would drop out, nothing. Use my truck light to check chamber, OH CRAP, round is chambered. How in the heck did this happen? I was one step away from dry firing before putting the gun up. Used butter knife to remove round. I have 15k rounds of semi experience through my Colt 6920, AP .308 and my crappy home made 6.8. I have never had this type of feed problems. If this happens at my range and I misfire..... Learned two lessons here. Gun jams stop and take it home and strip it down. Second, I will flag my gun every time to check the chamber! Not happy to know that LWRC is having problems with this gun. At SHOT I talked to their staff, “everything’s great, you are going to love that gun...but check out this lighter version with the Proof barrel”, which would have perfect for me to lighten the load. I am bummed. We will see how fast LWRC can fix this problem. I can not recommend the Mk2 to anyone at this time.
That is the exact same problem I was having, except when the rounds were halfway up the ramps where you couldn't drop the mag because the round was still half way up the ramps and you can't get the bolt to push the round into battery because its halfway jammed halfway in the mag with the rim below the bolt at the same time, I used a small flat head screw driver (like for tightening screws on a pair of glasses) to grab the rim on the case and pulled the round back into the mag (it wasn't easy) so that I could then drop the mag to clear the rifle. I too had issues were the rifle would chamber a round and it would take me dropping the bolt on the chambered round 5-10 times before it would extract the unfired round from the chamber. I am both glad and at the same time sad to hear that I'm not the only on with this issue. Well when I get mine back I will let you know if they were able to fix it, so that if so you know that your will also be able to be fixed. Thanks for the post and let me know if you are having any other problems like light primer strikes

The LWRC mk2 must be very hit or miss. A friend of mine had one that shot so well that another friend bought a slightly used one at the LGS. Guess he found out why it was traded in. Gun would not feed and even single fed had extraction problems and accuracy was about 3" at 100 yds. He has sent it back 2 or 3 times and it now functions fine but accuracy has not improved. He is considering selling it or continuing to send it back until made right. Very frustrating for owners for sure...
The LWRC mk2 was very high on my list...been saving my money to get one after hearing about the CSASS... was so happy they had improved over the original REPR which was reported to be very reliable / but more of a Battle rifle then precision ...After all the negative reports .. seems like there MK2 production guns are not in the same class as the CSASS LWRC produced for the military .... I heard a rumor that they changed the the upper in mk2 production guns from the original csass aerospace-grade 7075 aluminum for the receivers .. again just a rumor .. But for the price of 4k+ i think i'm going to take a look at the SWORD MK 17 and SIG 716 GEN2DMR ... good luck guys hope they get it worked out / just cant wait anymore to spend my money .. https://sword-int.com/mk-17/
Yes, there is a difference. The upper and lower are made differently. One is full billet and the other is cast. This is mentioned in a few reviews. The CSASS is all billet.
Were you loading the mag into the gun with the bolt catch lever locked or loading the mag and short stroking to load the mag into the chamber? Just wondering? When I Lock the bolt back and release, the round is now loading fine. Never had a gun like this.
Damn, I was just looking at one of these. Pretty disappointing...
:-(
:-(
Yea but I nailed a bobcat at 248 yds last night. LERC told to lube it and use bolt catch to release the bolt to chamber the load. They told me that it will take around 40 rounds to break in the very stiff spring. I shot a box of ammo yesterday with no problems.
Great to hear and thanks for the update, but I will hold off a little before I decide.
Take care,
Ken
Take care,

Sucks you guys are having these issues. I have the old school version with the side charging handle and I love mine. Its a 1 moa gun all day long and have had zero problems.
Well my rifle showed up yesterday and after inspection they had indeed replaced the barrel. So I took it out to the range with several boxes of ammo (1-Federal XM80 ball, 2-FGMM 168gr., 1-FGMM 175gr., 1-Hornady Match 168gr., and 2-Hornady Match 178gr.) to see how it would do.
- I started with the XM80 149gr. to get it sited in and then shot groups with the remaining rounds- averaged about 1MOA- It functioned with out issue at gas block position 14.
- Next were the FGMM 168gr. (which on the paper work that came back with the rifle is what they said it was tested with)- averaged just under 1MOA - after each of the first couple rounds the rifle failed to cycle and failed to feed (round jammed between bolt face and barrel extension) the third and forth round at position 14. I turned the gas block to position 16 for another 5 rounds with same results. I then turned gas block to position 18 for another 5 rounds and yet again fail to cycle and fail to feed. I then turn the gas block all the way to position 20 and same results. I then screwed the gas block adjustment screw all the way out and wiped it down and inspected for clogged ports or damage-nothing, it had a little carbon on it but looked fine. screwed back in. I then set to position 16 and put another 5 rounds through it with same results as before, failure to cycle and failure to feed. I tried another 5 rounds at position 20 once more but still the same problems occurred. I then turned to position 0 with the gas off and shot the last 10 rounds by shooting the round then cycling the bolt by hand via charging handle and bolt release in which rounds ejected fine when the charging handle was pulled rearward and it chambered the rounds fine when the bolt release was pushed (best groups with this ammo were a result of cycling by hand).
- Then I moved on to the Hornady Match 168gr. rounds which my rifle previously had several issues with chambering and failing to fire before the rifle was sent to LWRC for repairs.- averaged 1-1 1/4MOA - I set the gas block to position 14 and fired a 3 rounds and then it failed to cycle, I then adjusted the gas block to position 16 and shot the remaining 2 rounds for that groups with no issues. After that I was able to shoot another 3 groups of 5 rounds with no issues what so ever.
- I then moved on to the Hornady Match 178gr. rounds which were by far the most problematic rounds before the rifle was sent in for repairs.- averaged around 3/4MOA - ( best group with this ammo 1/2MOA) With the position still at 16 I was able to shot 8 consecutive 5 round groups no issues what so ever.
- Finally I moved to the FGMM 175gr. - averaged 1MOA (could have been better but quit shooting after 2 groups do to functioning issues)- With the gas block still at position 16 I loaded up 5 rounds and fired a shot and it failed to cycle. I then adjusted the gas block to position 20 with no improvement, just the same issues I had before with the FGMM 168gr. rounds. So I the turned gas block to 0 and shot one more 5 round group with the rifle by cycling it by hand as I ended up doing with the FGMM 168gr. rounds previously. As it did previously, the group shot by manually cycling the rifle was just over 1/2MOA .
I took the rifle home cleaned it up a bit. Now I will see if they will send me some replacement components for the adjustable gas block or if I will once again have to send them the rifle... Also just a note, When I got my rifle back it was filthy with carbon build up in the break, hand guard, and chamber from not being cleaned after testing. Also the new barrel had tool makers all the way down the flutes were the ball nosed end mill being used was chipped (not a big deal and on a different note it shot great compared to the first barrel that came on the rifle), but for a $4200 rifle I would expect better quality.
update- I just talked to Rodney at LWRC about the issues with the FGMM and he gave me a few suggestions to try out tomorrow to see if I can get it working properly. I will let you all know how it goes

I then turned to position 0 with the gas off and shot the last 10 rounds by shooting the round then cycling the bolt by hand via charging handle and bolt release in which rounds ejected fine when the charging handle was pulled rearward and it chambered the rounds fine when the bolt release was pushed (best groups with this ammo were a result of cycling by hand).
- Then I moved on to the Hornady Match 168gr. rounds which my rifle previously had several issues with chambering and failing to fire before the rifle was sent to LWRC for repairs.- averaged 1-1 1/4MOA - I set the gas block to position 14 and fired a 3 rounds and then it failed to cycle, I then adjusted the gas block to position 16 and shot the remaining 2 rounds for that groups with no issues. After that I was able to shoot another 3 groups of 5 rounds with no issues what so ever.
- I then moved on to the Hornady Match 178gr. rounds which were by far the most problematic rounds before the rifle was sent in for repairs.- averaged around 3/4MOA - ( best group with this ammo 1/2MOA) With the position still at 16 I was able to shot 8 consecutive 5 round groups no issues what so ever.
- Finally I moved to the FGMM 175gr. - averaged 1MOA (could have been better but quit shooting after 2 groups do to functioning issues)- With the gas block still at position 16 I loaded up 5 rounds and fired a shot and it failed to cycle. I then adjusted the gas block to position 20 with no improvement, just the same issues I had before with the FGMM 168gr. rounds. So I the turned gas block to 0 and shot one more 5 round group with the rifle by cycling it by hand as I ended up doing with the FGMM 168gr. rounds previously. As it did previously, the group shot by manually cycling the rifle was just over 1/2MOA .
I took the rifle home cleaned it up a bit. Now I will see if they will send me some replacement components for the adjustable gas block or if I will once again have to send them the rifle... Also just a note, When I got my rifle back it was filthy with carbon build up in the break, hand guard, and chamber from not being cleaned after testing. Also the new barrel had tool makers all the way down the flutes were the ball nosed end mill being used was chipped (not a big deal and on a different note it shot great compared to the first barrel that came on the rifle), but for a $4200 rifle I would expect better quality.
update- I just talked to Rodney at LWRC about the issues with the FGMM and he gave me a few suggestions to try out tomorrow to see if I can get it working properly. I will let you all know how it goes
