Rock River Arms LAR-BT3 Operator DMR 308 Win 20+1 20" Semi-Auto Rifle

The Rock River Arms LAR-BT3 Operator DMR is a semi-auto .308 Winchester designated marksman rifle purpose-built for long-range accuracy and hard use. Chambered in 308 Win/7.62 NATO and built on the proven AR-10 platform, this rifle pairs a 20" threaded barrel with a 1:10" twist to deliver reliable performance across duty, hunting, and precision applications.

At the core of the BT-3 is a billet aluminum receiver finished in blued/black, dressed out with a crisp two-stage match trigger, a manual safety selector switch, and an A2 flash hider at the muzzle. A 17" lightweight M-Lok handguard provides generous real estate for accessories while keeping the rifle well balanced for off-hand and supported shooting alike.

The Operator DMR configuration is rounded out with a BCM SOPMOD stock, a Hogue Beavertail grip, and Magpul MBUS Pro front and rear sights for fast target acquisition right out of the box. Measuring 38.50" overall and weighing 8.96 lbs, this rifle shoulders naturally and handles with confidence for right-hand shooters.

Featuring a 20+1 capacity and shipping with a rifle case, the LAR-BT3 Operator DMR is ready to deploy from the moment it arrives.
