Rock River Arms releases its latest MSR with the BT3 Operator ETR Carbine, chambered in .308. Tailored for law enforcement applications, the rifle offers feature enhancements that provide 1.5 MOA accuracy. Not to mention, its optimized twist rate stabilizes a wide range of bullet weights for maximum versatility and effectiveness.
Rock River Arms BT3 Operator ETR Carbine
The RRA LAR-BT3 billet lower offers feature enhancements designed for optimal control and comfort. Specifically, the Operator includes the Hogue Beavertail Grip with ergonomics that provide a secure and comfortable grip. Likewise, the RRA 6-Position NSP-2 Car Stock allows users to dial in the length of pull for the perfect fit.
Featuring an RRA LAR-BT3 billet A4 upper, the Operator is equipped with a 16-inch chrome-lined barrel, providing enhanced corrosion resistance. Likewise, a 1:10 twist rate provides consistent tight groupings and performance of the .308 round. Additionally, the optimized twist rate helps stabilize a wide range of bullet weights to provide versatility and overall effectiveness.
The barrel, with A2 flash hider and mid-length gas system with low profile gas block, is housed within the RRA 13-inch Lightweight Free Float Rail. With a full-length Picatinny rail along the top and M-LOK slots running the sides, there is ample room for optics, lights, and other accessories.
An RRA Two Stage Ultra Match Trigger sends rounds downrange with a smooth, precise trigger pull. As a result, the BT3 Operator boasts an accuracy of 1.5 MOA at 100 yards. Each carbine ships with one magazine with a capacity dependent on the state of purchase. The standard magazine size is 20 rounds, but prohibitive states receive a 10-round magazine.
