The Rock River Arms LAR-BT3 X-1 in .308 Winchester (brand part no. XBT31752B.V1) is a semi-auto precision rifle built around a 20-inch, fluted, bead-blasted stainless barrel. Rock River Arms wraps the barrel in a free-float 17-inch aluminum M-LOK handguard and fits the rifle with a Magpul Gen 3 PRS precision stock and a Hogue grip. The RRA Hunter muzzle brake tames recoil, and the rifle uses an RRA Star safety selector along with an oversize Winter trigger guard for gloved operation. It ships in a Rock River case with one magazine included and runs standard P-mags. Among precision .308 platforms in the AR rifles category, the LAR-BT3 X-1 favors long-range shooters who want an adjustable precision stock on a .308 AR platform.
