Rock River Arms, Inc. produces American-made, custom-built rifles and pistols, including their LAR-15, a precision tactical rifle contracted by the DEA. The LAR-15 Predator Pursuit is notable for its air-gauged stainless steel, heavy match barrel, the same barrel used on Rock River Arms' National Match rifles. The barrel is over a pound lighter than their Varmint barrel and accurate up to 3/4 MOA at 100 yards. The Predator Pursuit also features RRA's .223 Wylde chamber, designed as a Match chambering for semi-automatic rifles. The chamber is relieved in the case body to aid in extraction and has a shorter throat for improved accuracy. The rifle comes standard with a forged A4 upper receiver, a light varmint gas block with a sight rail, a two-stage match trigger, RRA's Winter Trigger Guard, a Hogue rubber pistol grip, an aluminum free-floating tube handgaurd, and an A2 buttstock. 20-round magazine and RRA case included. 1:8 twist.
