Re: DPMS MK12 barrel
I know everybody likes to knock DPMS gear but I actually heard their barrels are alright. It wouldn't be my first choice for an SPR build (Douglas from HCS would), I'm sure it will serve its intended purpose. Post some pics when she's built!!

Re: DPMS MK12 barrel
I wondered about these simply because of the price. When I was looking, it sounded like they got consistently good reviews for accuracy.
One thing that was mentioned was that the barrel was not contoured correctly for the Ops Inc collar. If you are going to use the Ops Inc, I would check to see if this is true and if it has been fixed.

Re: DPMS MK12 barrel
i guess dpms has mixed reviews, but ive had two 16 inchers that are plenty accurate.
mil.dot, well good thing i purchased a SF brake instead.

Re: DPMS MK12 barrel
I have their mini-sass 1:8 heavy 18" barrel on an SPR, and I think they are decent barrels. YRMV...but with bulk 62grs, I have shot under 1moa groups at 100yds and hit steel at over 1000yds.

Same barrel, same results. Not bad for a $200 hunk of steel.

Re: DPMS MK12 barrel
The gas block sucks, but the barrel is accurate. I'm punching .460 MOA with mine that I bought years ago on a whim using hand loaded Mk262 Mod 1.

Most people that give DPMS barrels bad reviews are one of 2
1. A DPMS out shoot their more expensive barrel.
2. They never owned a DPMS.
I would put my DPMS up against any gun and I have won lots of money at the range when people think "Oh it's just a DPMS!"
I will be using the same barrel for my next build.

Re: DPMS MK12 barrel
I can echo the positive feedback. I have been impressed with the accuracy from my DPMS MK12 barrel.

Re: DPMS MK12 barrel
I bought one recently and while I haven't put a lot of rounds down it yet, I have yet to have it print a 5 shot group at 100yds of more than 1.25". So far I've only been working on loads with 77gr smk's but I may try some 75gr Hornady bthp soon because I haven't been able to get a consistent .5-.6" load yet with the smk's.
I have confidence that it will shoot that well with the right load due to my past experience with DPMS barrels, so I will keep on trying to find that .5" load. I have yet to see one prove me wrong, although I'm sure there are some out there that aren't up to snuff. Any manufacturer can turn out a lemon, some less/more than others.

Re: DPMS MK12 barrel
I just went through this. I decided to go WOA but the DPMS was a very high contender. All the ACTUAL reviews I could find on the mini-SASS barrel were good

Re: DPMS MK12 barrel
Not the OP, but I really appreciate the feedback from folks who have first-hand experience with this barrel.
I'm seriously looking into a "budget precision AR" along the SPR concept and if the DPMS Mark 12 tube is capable of 1 MOA or better accuracy with a load it likes, then it appears to be a good candidate for my first AR upper build.

Re: DPMS MK12 barrel
For me it came down to the WOA was ~$40 more and carries a slightly better rep. had the DPMS been somewhat more of a cost savings I would have got it. I also didn't want fluting as I have something else planned so that was the final nod

Re: DPMS MK12 barrel
I bought one of these barrels from Brownells at a great price for an SPR type build. At first I was not too impressed with the accuracy. It got much better as I kept shooting it and working with different loads. It will shoot solid MOA groups if I do my part and I've had no problems with it. It cleans up easily. I would buy another.

Re: DPMS MK12 barrel
I too can say this is a good barrel. Sub MOA with factory match ammo. It's true the Ops Inc collar won't fit, but not a problem for me since I already had AAC.

Re: DPMS MK12 barrel
I bought one of these and am more than satisfied with 5shot groups of .5-1" depending on the load.
Just don't look down the bore with a borescope. UGLY! but it shoots. The olympic barrel it replaced looks like a match grade barrel. Very smooth and no tool marks. No wonder it shot so well.

It will look better after a couple hundred rounds. When I got my sass my gunsmith thought the barrel was DOA but it shot well too.
I sent off an AR barrel to be nitrided a month ago, I get it tomorrow according to UPS, fingers crossed...

Re: DPMS MK12 barrel
Ordered this barrel for my budget SPR build. Should have it tomorrow but will have to wait a few days to shoot it because my dumbass forgot to order a new barrel nut. Hopefully shoots as well as you guys say.

Re: DPMS MK12 barrel
Let us know how it shoots! I almost bought one. i got this one instead AR15 performance threaded 5/8"x24 for my can. It is melonite treated carbon steel. Hopefully it'll get good groups and last a while. My second choice was the dpms barrels.

If you go with the mini sass you well need a special barrel nut. This barrel is about .050" larger OD then the barrel nuts ID. I believe DPMS makes a hand guard/barrel nut combo or you can just turn a oem barrel nut to fit. I had to remove about .020"+/- from the nuts ID.

My results:
Barrel doesn't have many rounds through it yet, so I expect it to get a bit better as it wears in.
Groups were shot on a calm, clear day with a Lead Sled and 3.5-10x scope. Not sure of velocity as I do not have a chronograph. Upper was a no-name "mil-spec" off the Arfcom EE that I lapped. Rifle has a Geissele SSA trigger. Brass was mixed year LC. I'm not sure what primers were used - most likely CCI SR or #41. Ammo was loaded with Lee dies.
For a sub $200 barrel, I'm quite pleased with the results.

Re: DPMS MK12 barrel
Took it out today and shot some black hills seconds 77gr 556, tightest it shot was 1/2 moa at 100 but mostly shot 3/4 to 1 min. Im going to try some handloads and see how it likes them.

Re: DPMS MK12 barrel
Has anybody tried this barrel with the Nosler CC 77s? I can't get them to shoot with Varget. I also have some Hornady 75 gr. ammo that shoots under an inch easy with a RRA upper and this barrel hates it as well.

Re: DPMS MK12 barrel
Nope, went by the Nosler manual and ran these and SMKs at 2.260. Although I'm over a grain above what Nosler said was there accuracy load with a Pac-Nor barrel. I guess I can try seating them deeper if they like jumping this much.

I have the DPMS MK12 barrel on my most recent AR. I have shot 75gr Hornady BTHP with sub 1in groups and 55gr hornady FMJBT also with sub 1in groups at 100yds. I hope to take the 75gr out to 600yds this coming spring.

Re: DPMS MK12 barrel
Finally had time to load some ammo, this barrel with handloads put a smile on my face.
77smk, all loads with varget shot well under moa.
1" dots at 100Y
Also, had a small face lift, i cerakoted it burnt bronze and media blasted the barrel and shot clear cerakote over it. Stock and grip are cerakoted armor black.

fngmike, The 77 grain Nosler CC's shoot the best in my rifle with this barrel. I haven't loaded them with varget yet but that's what I'm planning on using next, all I had was CFE223. I also had them seated at 2.260

Bcp,
Overall, i really like them, quality, fit, function and price theyre hard to beat. Free floating and lock up is tight. Unless youre trying to build a spec mod 0 or just want the looks of the cf rail, you cant beat the midwest gen2 rail

Re: DPMS MK12 barrel
Hell I'm glad I'm not the only one that got that barrel for a "budget" mk12 build. I looked through a number of peoples mk12 build pictures and quickly gave up on the idea, everyone had super legit (expensive) components I wasn't willing to match. As for accuracy of the dmps barrel i put a 20rnd clip in the center(ish) of a steel torso size target at 500yds with some hornady steel match (75grn I think?) I have a couple boxes of black hills 77otm but now I'm to chicken to shoot em, no telling when I'll be able to get em again for the ~$35 I payed if ever.. I'm cheap
