Rock River Arms recently announced the company’s first AR-platform rifle chambered for the .17 HMR cartridge called the RRA .17 HMR, which joins the company’s LAR-22 rifle lineup to round out its rimfire long gun offerings.
Built on the RRA A4 billet upper receiver and forged A2 lower, the RRA .17 HMR is fronted by a precision-manufactured 41V50 CMV 18-inch barrel rifled with a 1:9-inch 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.
Adding to the precision barrel is Rock River Arms’ National Match Ultra Match two-stage trigger—a key ingredient to enhancing the shooter’s accuracy potential. In addition, the rifle has a rear charging handle, along with a winter trigger guard for use when wearing gloves.
Furthermore, the RRA .17 HMR is fitted with an ergonomic Magpul MOE grip, adjustable Magpul MOE SL-K six-position stock and the company’s lightweight 15-inch free-float handguard with M-LOK compatibility. A 10-round magazine is also included.
Overall weight with the magazine empty is 6¾ pounds. With the stock collapsed the length is 33½ inches.
MSRP for the new Rock River Arms RRA .17 HMR is $1,300. Go to rockriverarms.com.
