DPMS AR-10 LR-.308 Cycle Failure | Sniper's Hide Forum
Nov 23, 2021 · The so-called "standard" buffer in these DPMS, PSA, etc 308 ARs is really a standard AR15 buffer that weighs ~3 oz. They were designed for 223/556 systems. The original Armalite (not the same co as today) AR10 was designed to run a 5.4 oz buffer to handle the 308 round. That's the same weight as a H3 buffer.

What do you shoot .308 or 7.62 in dpms?? - Sniper's Hide

DPMS Mark 12 308's are in, what do you think?
Dec 22, 2008 · He has a Mark 12 in 7.62 that he says shoots 1.25 to 1.50 groups and is just as reliable. He loves both rifles.

Aero Precision - DPMS pattern - DPMS LR-308 General, Technical ...

This was my thinking. If I buy I would buy a Bushmaster XM10 rifle with a 16" barrel, it has almost everything I want. That will cost about $1000 give or take plus ...
When is a DPMS LR-308 not .308 ready? | Sniper's Hide Forum
Feb 6, 2010 · According to SAAMI, the MAX pressure for .308WIN is 62,000psi. MAX pressure I found stated for the 7.62 NATO was 58,000, some sources saying as low as 50,000. Any issues would likely be from headspace. 7.62 NATO rounds have a longer allowable length before failing headspace when compared to .308.

Question on DPMS .308 upper rail height... - Sniper's Hide
Aug 22, 2013. #1. So I bought a new DPMS assembled .308 upper with charging handle and FA from Midway a few months ago for my AR-.308 build. I have been buying pieces here and there and today found a screaming deal on a Troy .308 TRX battle rail (with "low" top rail).
