Rock River Arms OP1000BT Operator ETR | .308 Win | 16-inch

The Rock River Arms OP1000BT LAR-BT3 Operator ETR is a semiautomatic .308 Win carbine with a 16-inch threaded barrel and a lightweight 13-inch M-LOK handguard. It includes an extended charging handle, a two-stage match trigger and an RRA 6-position NSP2 stock, and ships with a carrying case. For this platform, a rugged variable optic such as the Vortex Viper PST Gen II 1-6×24 pairs well and remains below typical $1000 price points.

Applications: medium-range precision shooting and hunting in environments where a compact .308 platform is preferred.
