ARMALITE AR10TAC18 | .308 Win | 18″ Barrel

The ArmaLite AR10TAC18 is an AR-10 style semi-automatic rifle chambered for .308 Win / 7.62 NATO with an 18" barrel and a 25+1 magazine capacity. It ships configured with Magpul MBUS flip-up sights, a Magpul STR multi-position collapsible stock and a 15″ KeyMod free-floating handguard for accessory mounting. This configuration is built for sustained precision and repeatable performance in field or duty roles.

A suitable optic under $1000 that pairs well with this rifle is the Vortex Viper PST Gen II 1-6×24 for close-to-midsize engagements and low-power variable versatility. Applications include precision work and duty or range use where the .308 platform’s performance at extended distances is required.
