AR-10 ACCESSORIES

The receiver was made from forged and machined aluminum to reduce weight. The bolt locked into an extension on the barrel instead of the receiver allowing for a lightweight receiver while not reducing the strength of the bolt locking mechanism. On a few prototype guns, a all-aluminum ('Sullaloy') or aluminum/steel barrel was fitted at the insistence of George Sullivan, Armalite's president, though all production AR-10s utilized a solid steel barrel. The stock was made from a plastic-reinforced fiberglass with a core of rigid plastic foam. The handguards and pistol grip were also fiberglass. The AR-10's method of rotary bolt locking, straight-line recoil, and gas operation enhanced its inherent accuracy. At the time, the AR-10 was the most accurate standard-issue selective-fire military rifle ever built.
