The RRA 17 HMR from Rock River Arms joins the company’s LAR-22 rifle lineup to round out its rimfire long-gun offerings. Built upon the RRA A4 billet upper receiver and forged A2 lower, the RRA 17 HMR is fronted by a 41V50 CMV 18-inch barrel rifled with a 1:9 twist. The cycle of operation is managed by a gas impingement, delayed blowback system that delivers reliable cycling of 15.5- to 20-grain cartridges. Other key features include RRA’s NM Ultra Match two-stage trigger, free-float handguard with M-Lok compatibility, a rear charging handle, 10-round magazine and ergonomic Magpul MOE grip and SL-K six-position stock. 

MSRP: $1,300.
