The ArmaLite AR-10 Competition Rifle in .308 Winchester/7.62x51mm NATO (brand part no. AR103GN13) is a semi-auto AR-10-platform rifle built around a 13-inch match-grade stainless steel barrel, pinned and welded to an ArmaLite Tactical Brake to keep the configuration outside NFA short-barrel requirements. ArmaLite pairs the barrel with a Timney 667S single-stage drop-in trigger and wraps it in a 12-inch M-LOK free-float competition handguard. The rifle includes an adjustable Luth-AR MBA-1 stock, an ambidextrous Radian Raptor charging handle, and MIL-SPEC 7075 upper and lower receivers, finished in black. Among AR-10-platform competition rifles in the AR rifles category, the AR-10 Competition favors shooters who want a compact .308 platform with a genuine drop-in match trigger.
