I recently tested a DPMS LR308 for a friend. It is bascially new with a 24" bull barrel, a proven Meopta 6.5x20 scope and a McCormick trigger. He is only using Georgia Arms ammo right now breaking it in. Both of us shot it with the same results. The 1st 5 shot group is an actual group. After waiting about 10 min, another group was fired and they strung horizontally about 4". The shots looked like they had been laid out horizontally with a ruler. The range was 100yds and shots were fired off of a solid bench and rest. The rifle was cleaned and the 5 fouling shots were fired before the groups. The conditions were hot and calm. Any ideas??

I shot a few hundred rounds of the Georgia Arms .308 Ammo a few years back, through a couple .308s. It was crappy--about on a par with CAVIM or FNM milsurp. 1.5 moa stuff at best.
Try a box of Federal Gold Medal match first before you conclude the gun won't shoot.

Thanks for the tip. I've never used Georgia Arms ammo, so I don't know anything about it. I wanted to shoot the load I shoot in my 700, but they're neck sized only and wouldn't chamber. I thought it was strange the rifle was shooting a normal shaped group first and then stringing horizontally on the second group from a cool barrel. I 'll tell him to try Gold Medal Match in the rifle and see what happens.
That's one of the really nice things about shooting a .308 Win; there's great match-grade factory ammo avail to help sort out stuff like this...
Is it me? The rifle? The ammo? The scope? At least the factory match grade stuff gets rid of one variable. I've had that doggone Federal Gold Medal ammo shoot down to 1/2 MOA at 600 yards... And am frustrated because it's very difficult for me to match that accuracy level.

ANYBODY know how to get in touch w/ DPMS? My LR-308 punches holes in primers w/ out-of-the-box ammo. The little punched out piece ends up in the bolt firing pin recess. Help!
I believe DPMS as a company has faded into history last I read. I have a 223 Bull 20" that is an absolute nail driver with 60 gn Hornady V-Max's and Varget. Don't shoot it very much these days but it's a lot of fun when I do.
ARs are sooooo simple to work on.... May be a simple problem as an out of spec firing pin... I don't think I would be mailing off an AR with Biden in office... Order another firing pin from someplace like KAK industries or Windham weaponry... Or simply measure it and find the spec online , check for a sharp instead of round tip etc... Worse case scenario you end up with a few spare parts that during this time is not a bad thing... Even a spare bolt or BCG is a great thing to own....
Palmetto bought DPMS
I don’t see DPMS in JJE‘s current portfolio, guess it’s gone.
Anyone know if a AR bolt can be bushed?
If this is true , fix it yourself....
A new one from KAK is $100 I don't know if it would be cost effective...

Depending on the load I pierce primers in my Rem. R-25 .243 (built by DPMS) if they are not CCI #34 7.62 primers developed for the M14/M1A. Also Fed. match primers will fire when closing the bolt during AR Tactical matches. (single loading) Most factory .308 ammo is built for bolt guns, except M118LR developed for military AR-10 use.
Pierced AR primers seem off thread; but search here; I did a write up on my DPMS and that included firing pin/primer issues and my resolution to them.
As to the OP post, Forum Boss has it right, try different ammo first. Fed GMM 168 and fed GMM 175 are benchmarks for almost all ARs. Take pics of your brass (case heads) and post them here, we can help you verify your gas system is in tune if you're not sure what to look for. Post some groups too, I'd recommend 5-round groups and 1 of them single feed, the rest feed from the mag.
Alternates to try if Fed GMMs aren't available, nosler Cust. Comp. or Hornady Match.
I'm skipping a ton of info, so keep is posted on how the ammo change goes.

Some good advice for the OP in this thread but I still would simply start with the firing pin... It shouldn't need anything extra to make it work , it should work right out of the box with factory ammo.... I use soft CCI Primers in my AR platform rifles and have never had a problem BUT I do take every precaution still and don't have pierced primers... I can tell you from first hand experience that not all companies and builders are created equal....
One of the companies listed here is a prime example from my experience.... One rifle bought from them came in scratched up , over gassed , you have to pry the charge handel in and out , the ejector spring was garbage brand new and I could keep going.... All but the scratches I can fix right on my kitchen table and did... My point is some are problem children and I have even seen colts brand new with problems but any can be fixed easy... Most are mass production so QC is always going to be a problem... Somethings just are not checked basically and a firing pin that's just a hair to long etc will make it out of the door...
I would not send it back over a ten dollar part that takes no tools to change... Right now we are hearing horror stories about not getting guns back for months and not being able to contact anyone either... If you don't know how to fix it I couldn't think of a better time to learn... These companies way over gas guns on purpose , to keep the phone from ringing when people shoot cheap crap ammo in them , to make them cycle... So I don't doubt anything anymore... Pull it apart and take a very close look at things , doesn't cost a penny...

That (new bolt head w/ smaller hole & firing pin to fit) is what I figure I had to do. Harder primers may be a solution, but I'm not sure which ones to get, & anyway, primers are hard to find on East Coast now.
Wanted to see -first- if DPMS had developed a solution. But, from other posts, it seems DPMS is defunct.
Thanks for all you guys help!!

So is Georgia ammo remanufactured or custom loaded using customers brass, if it is remanufactured I doubt it is only neck sized. So it should work in any SAAMI spec 308 chamber.
