ArmaLite AR-10T Close-up of an AR-10 National Match receiver. In 1995, former Army Ordnance officer Mark Westrom, owner of Eagle Arms, purchased the ArmaLite brand and the company became ArmaLite Inc. Shortly thereafter, ArmaLite Inc. introduced the completely new semi-automatic-only AR-10B rifle series.
The resulting COAL of 2.300" is only 1.02 mm longer than the maximum COAL for chambering a cartridge in the smaller AR-15; however, the 45 Raptor chamber pressure is allowed to be as high as 62,000 PSI. This means that the stronger AR-10 receiver and bolt carrier group is needed for shooting this cartridge.
Attaching the barrel to the receiver using a barrel nut and a barrel with a shoulder is an alternative to action threads, which has been used in firearms such as the Sten gun and AR-15.

ArmaLite AR-10. In 1955, Stoner completed initial design work on the revolutionary ArmaLite AR-10, a lightweight (3.29 kg (7.25 lb)) select-fire infantry rifle in 7.62×51mm NATO caliber. Besides featuring the Stoner bolt and carrier piston system, the AR-10 stock was in line with the bore to reduce muzzle rise, especially during automatic fire.
It had a flat top upper receiver with a Mil-Std 1913 rail for mounting optics and a 2-stage match grade trigger. The bolt carrier was similar to the AR-10's, being chrome plated and having a captive firing pin retainer pin. The SR-25 was designed specifically to fire 168 gr (10.9 g) open-tip match cartridges.
