Description
The Rock River Arms LAR-BT3 Operator ETR Carbine is a Semi-Auto tactical rifle chambered in 308 Win (7.62 NATO), built on RRA’s AR-10 pattern platform and purpose-designed for duty, defense and long-range work. This OP1000BT configuration pairs a 16″ chrome-lined, threaded barrel with a classic A2 Flash Hider, a 1:10″ twist and a 13″ lightweight M-LOK handguard for accessory mounting.
At the center of the action is an aluminum lower equipped with RRA’s signature RRA Star safety and a crisp Two Stage Match trigger. Up top, the rifle is optic-ready with no iron sights installed, and an extended charging handle aids positive manipulation. The carbine wears a Blued/Black finish, measures 33″ overall and weighs in at just 6.40 lbs, striking a useful balance between portability and steady shooting.
The shooter interface is handled by the RRA 6-position NSP2 carbine stock for adjustable length of pull and a Hogue rubber beavertail pistol grip for fatigue-resistant control. A 20+1 detachable magazine is supplied. The rifle ships with a hard carrying case from the factory and is set up for right-hand shooters.
