With the release of its new patent-pending Caliber Matched Gas System (CAMGAS) barrels, PROOF Research has eliminated the issues traditionally associated with building 6.5mm and .260 rifles on 308 AR AR-10 platforms. Until now, AR-variant shooters looking for ballistic advantages from either of these calibers were faced with excessive bore pressures that necessitated makeshift solutions such as clipping buffer springs, adjusting buffer weights, and/or relying on adjustable gas blocks, to keep their rifles functioning properly.
PROOF’s R&D team has solved the overpressure issue with gas systems tuned specifically to the cartridge/barrel-length combination. “By moving the gas port, the pressure in the bore is given time to reduce to that comparable of a .308 Winchester with a rifle-length gas system, which is what the 308 AR AR-10 system was designed around,” said Greg Hamilton, PROOF’s research-and-development weapons specialist who’s also a 3-Gun and PRS competitive shooter. “The recoil impulse is noticeably smoother, which helps keep you on target while taking advantage of a more efficient projectile. Case extraction is also easier, with less case-head smearing, so the brass is in much better condition for reloading.”read more
Based on a Hiperfire trigger the Echo Trigger has a unique feature that allows an AR to fire when the trigger is pulled and also when released. This translate into much more expensive trips to the gun range. My two initial observations are the trigger is quite expensive and also looks to be pretty complex. At this time I cannot confirm how this trigger functions in a 308 AR or AR-10. If anyone has any experience with the echo trigger drop us a line.read more

As I mentioned elsewhere on the site Bartlein Barrels known to make some of the most accurate rifle barrels in the world does not make barrels for the 308 AR, AR .308 platform. Instead they send customers to Craddock Precision. In turn Craddock is quickly making a name for themselves for making the most accurate 6.5 Creedmoor and .308 Winchester 308 AR Barrels from Bartlein and Criterion Barrel blanks. Now they are very forward thinking in offering the same accurate barrels for DPMS GII (DPMS G2) and equivalent riflesread more

You can read many reviews of the Precision Armament M41 muzzle brake….read more

As if the 308 AR versus AR-10® platform debate isn’t confusing enough Armalite brings confusion to their own platform. Armalite AR-10 lowers are available in two styles. The original AR-10 A series and the AR-10 B series.
Why does Armalite offer two different AR-10 lowers? Original Armalite “waffle” magazines are actually the basis of DPMS LR-308 and KAC SR-25 magazines. During the 1994 Bill Clinton Assault Weapon Armalite decided to switch designs to the modified M14 magazines to ensure customers would have an ample supply of 308 magazines.read more
