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.

RRA .17 HMR
About its new RRA .17 HMR, Rock River Arms said, “this rifle is ideally suited for rimfire fans looking for an accurate and reliable varmint buster or for a fun gun to ring steel across the .17 HMR’s effective ballistic range.”

 

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.
