The "New" Barrett MRAD Thread!!!!!!

[cypriss32]

Took my mrad out today. I forgot how well this rifle shoots. Put 3 shots out of 3 on 10” 1k with my 308 conversion.

How are the Proof barrels? I have a 300prc carbon 28” and was considering buying 6.5 creed barrel stainless barrel.

Can anyone confirm if I can run a Surefire SOCOM RC2 762 on the MRAD 300 Norma Mag by using the Surefire 3/4x24 338 muzzle brake? This is my first Magnum round and didn't realize the barrel had 3/4x24 threads. I think I'll get the AML338 but would prefer to not wait a year to shoot this suppressed if I can use my SF can in the mean time.

In case this helps anyone else, here is my answer from SF:

The 338 muzzle device only fits a 338 suppressor .

The 762 suppressor WILL NOT mount to the 338 muzzle device . The SOCOM762 RC2 is rated up to normal 300 win mag pressures.

If 300 NORMA MAG is exceeding those pressure then I would suggest getting the larger caliber 338 suppressor to be on the safe side.

I recently purchased a 300prc proof cf barrel for my mrad but have been wanting to pick up something more prs oriented. Is there anybody that would like to trade barrels or possibly take my 300prc barrel off my hands?

Sight height question:

Anyone running a 34 mm maintube in a mount that is at a height of 1.535 on their MRAD?

If so, what's your sight height from the centerline of the bore to the middle of your maintube?

Mine came in at 3.7 inches, but I want to double check that before I run some ballistic calculations.

I just upgraded my Razor Gen 2 to the Gen3 that is 6x and I think it's fine. Think it complements the Tugentsen well. View attachment 7942170

Digging up an old post here but, what height mount are you running on this setup? I get my MRAD in a few days and already have a Razor Gen 3 in a 1.181” Spuhr mount I’m going to pull of another rifle. Pretty confident the objective wont clear the rail with that height so curious what the best height is. Thanks in advanced.

1.181 is too low, I put 1.5 on gen 3.
(This is an old project, I'm waiting for Mrad)

Did you get this resolved by Barrett?

I think many of us are curious how this process went or is going.

Update**** Barrett quickly replaced the upper receiver and returned like new. The only complaint is they returned the trigger to ~3.5lbs...which was annoying.

They required you to send the lower receiver? Also, did the cerakote end up matching up well?

Yes. I sent the complete rifle back. The cerakote was matched well.

Anybody unable to get a 5/8 Area 419 adapter seated against the muzzle shoulder of their 30cal barrel? Looks like I run out internal threads on the multiple adapters I tried.

Yep, looks like the Hellfire is 0.645” max thread length and I’m measuring the factory barrel at ~0.675” shoulder to muzzle.

Gonna try some TBAC peel washers. Need about .03” worth. Noticed there’s no thread relief either so hopefully no problem.

300PRC. Got a 5-shot group of 1/4 MOA at 200 yards. Bugholes is 30 minutes from Barrett and he knows folks there. I was his first maker's kit and since then he has done a bunch. The jam nut takes 120 ft-lbs so not sure what Barrett uses to get a grip on the round nut but Bugholes machines flats in the nut to precisely torque. It also allows you to remove with a standard wrench if there is ever a need. Cerakote FDE is by me.
My 33XC printed a 5-shot 0.20 MOA group at 500 yards with very little wind. Whatever Bugholes is doing they are doing it well. My 41XC should be here in two weeks but that is going into a dedicated build-Defiance Rebel, Bartlein ModdBB 34" with Terminator T5, and Cadex Dual-Strike chassis. View attachment 8081139

Very curious about these bughole barrels. Will you send more pics please?

 

[Burke888]

Will a 20MOA Nightforce scope mount still allow for the rifle to be zeroed at 100 yards?

I have 30MOA picatini and 20MOA Spure mount and zeeroed on 100m vitout problems

 

[mike10]

I've had a prototype model for a while now and it is a very nice upgrade.


I've got the MDT MLOK weights on mine. Works just fine and doesn't look too bad.

Who did your custom barrel and what are the specs?

 

[TheOE800]

That ATACR and mount are contract specials IIRC, not available otherwise. The mount is not different per se, only marked differently.

 

[ney1]

I have noticed that the folded length of the Mk22 rifle is not published anywhere. Would it be possible for you to measure the folded length and report it here? In analyzing photos then it appears that the button is the rearmost portion of the rifle, if you could measure to that furthest point I'd sure appreciate it.

 

[ney1]

Thanks!

Great taste with the MK22

[tacguns]

I have the MK22 suppressor and it is big but quieter than I thought it would be on 300 PRC and 300 Norma sounds like a 308 with a 30 cal can I love it

 

[tacguns]

Oh yeah and if you’re going to switch between cal you won’t have to buy other brakes and the brakes are very effective

Nice rifle and optic. Post pics of how it shoots when you start grouping it.

 

[That_Bearded_Guy]

Finally got my MRAD out for her inaugural range trip yesterday. What an amazing rifle!

Here are a couple 5 shot groups from yesterday shooting 168g Federal Gold Medal Match .308 out of the 24" fluted barrel. Black dot high right of each group was the aiming point. I shot the group on the right first, completely removed + re-installed the barrel, and shot the group on the left. Virtually no POI shift. Dime for group size reference.

Tested out my 300 PRC barrel as well and that barrel shot just as good. Interestingly the 300 PRC shot 2.1 mils high from my .308 zero. I expected it to be high but this seemed like a lot. Anyone else have an example of POI shifts between different chambering out of their MRADs?

 

[Zolar]

 

[PrecisionRifleGuy]

A few months back I had the opportunity to run some rounds through my mates 300PRC MRAD. I come from the world of running Accuracy International rifles. I have to say the MRAD was excellent and dare I say it almost as good as my AI. haha.

I kinda want to buy one myself now.

 

[Pseudohero]

I just picked up an MRAD in 300 prc and have had it out a few times. It is simply the best gun purchase I have made. I have some high end gas guns but the MRAD makes me smile just thinking about it. I have a proof 6.5 cm barrel on order and may get a 308 as well. The question I have for you gentleman is….

Should I buy a 338 Norma barrel? It seems to me that the 300 norma only gives 100 ft/second over the prc with the same projectile but the 338 puts alot more energy on target. I don't currently reload but have in the past and have all my gear in storage. Having said that I would prefer to buy ammo and imagine that there will be some awesome loads coming out in the near future. I can get a pretty good deal on a barrel and figure that with military adoption that round is going only to be more available in the future. Like a kid with a few legos I just want more because merica!

My guess is the 300 PRC is going to do everything you’d ever want a 300 Norma to do so yeah, I think if you wanted to reload and invest in a new chambering, I’d look at the .338 offerings either Norma or Lapua Mag just to offer you something different than what the 300 PRC will already provide you. I own a 300 PRC MRAD and am in the same boat. Will likely end up going with .338 Norma Mag in the future.

I shoot all three - 300 Norma, 300 PRC, and 338 Norma (albeit in AXMC/AXSR platforms). I don't own an MRAD, but that's irrelevant. In factory ammo, the 300 PRC is a little less than half the cost to shoot than the others. The 300 Norma definitely outperforms the PRC, but good factory ammo (Berger 230 Hybrid Tactical) is double the cost of the PRC (Hornady 225 ELD Match). The Berger is a bit better ammo for ES/SD, which does make a difference at ELR distances. At present, there is NO good factory ammo offering for the 338 Norma that I have found, so it is a handload-only cartridge as far as I'm concerned. The Norma-branded factory ammo for the 338 is about the only one available, and it is WAY too conservative (slow). Of the three, with no restrictions (ie handloads OR factory ammo), I prefer 338 Norma > 300 Norma > 300 PRC, but the choice between the Normas is a very close race. If restricted to only shooting factory ammo out to unlimited distances, I'd rank them 300 Norma > 300 PRC > 338 Norma (338 Norma factory ammo sucks). If shooting factory ammo under 1 mile I'd rank them 300 PRC > 300 Norma > 338 Norma (here, 300 PRC > 300 Norma due to cost and no real advantage of the Norma at these distances, but beyond 1 mile then Norma is worth the extra cost).

Based on this, is there a common consensus on what projectile the MRAD likes best? For instance Ive heard the SCAR 17 was built around using the 147 grain stuff and my SCAR 17 shoots 147 grain handloads extremely well. I purchased the MRAD in 338 lapua and a 24" 308 conversion, a Nightforce ATACR 5-25, Spuhr mount, atlas bipod, accushot monopod, and Dear Air Primal. I ordered lapua cases, magnum large primers, and Retumbo (all I could find in stock). Looks like most of the higher end projectiles $1 a piece. Any input is appreciated

338 Norma was literally designed around the 300SMK, but it may not transition through transonic the best. 338LM was designed around a 250gr bullet, but shoots the 300gr fine. A lot of people like the 285 ELD in the LM, and I'd also look at the 300 A-Tips and Berger LRHTs.

The two I kept going back and forth on were the 300 grain SMK and the 285 grain Hornady ELD. I dont typically use anything but SMK in 556 and 308, but I have been very impressed with the 110 grain vmax for 300blk and the 750 grain AMAX for the 50BMG.

It maybe the case the 338 .mil version chamber wasn't spec for HPBT type projectiles.

Thank you. Ill grab a box of those to start. What powder are you using? I ordered some Retumbo, but keeping an eye on Discord for H1000

Edit: are all of you using the Hornady custom grade new dimension 338 lapua dies with the specific Hornady seater stem? Ive never been super impressed with Hornady dies

H1000. It was in stock on Hodgdon's website a few months back and I snagged (3) 8lb'ers. I had a bookmark on it and checked it everyday for months. I running Whidden 338NM dies.

Any more pics of the Area 419 Arca rail attachment?

 

[Pseudohero]

View attachment 8269389 This is a Blackhawk rifle bag for a reasonably compact MRAD set up. Ideally it would be wider with 2 inches more depth to double stack mags. It will fit an extra barrel and sleeve below the bipod. Had to reverse the mdt cye heavy to get it to fit. The mag pouches are mrad specific from arbor arms and are a more modern design than the ones tou can buy from Barrett.

I am surprised no companies have come up with an MRAD specific bag (other than the Armageddon gear which seems unavailable as a stand alone unit) but this will work for now.

 

[Pseudohero]

It may take me a few days but I will pull it out and take one. It is nice and well thought out. Fits perfectly.

I also have the Area 419 Rail - Very nice piece. Sadly only comes in dark earth, I had to cerakote mine to black to match my gun. Also arca Lock can be not used as needed with their design.

338 LM

 

[thedude824]

My current favorites. Does anyone know the correct process to change muzzle devices? I understand that the barrel should not be mounted in the receiver for risk of damaging the barrel extension. Are you wrapping the barrel in a towel and locking it in a vise? Do you need to heat it up first? Any idea how many ft lbs they are snugged to? Im still waiting on the Barrett recommended bit to swap from the 338LM to 308 to arrive. Id like to use my 30 cal suppressor for the 308 until the Dead Air Primal is approved.... in 10 months or more... ridiculous.

 

[Ehtacs]

After a certain amount of fiddling with muzzle devices, I ended up getting one of these barrel vises (curious about this one too) for next to my bench vise. I'm not sure it's paid for itself yet but it certainly makes wrangling barrels easier.

You used the Mechforce one on your Barrett MRAD to remove the muzzle device and it worked well? Im a buy once cry once guy and was about to spring for the Farrell unit at Brownells for $240. I will never be threading barrels onto actions. The occasional muzzle device is as far as I go outside of ARs and I've got the specific equipment for those. Saving $140 would be nice since it cost me 1k for bullets, powder, cases, and dies to get into 338 lapua. The costs associated with this platform have spiraled out of control unfortunately.

I haven't used it with the MRAD - sorry! I have used it for everything else including my MR762 (ever sit on a breaker bar? ) but I use the factory Mk22 muzzle with the Mk22 suppressor.
