A CO2-powered, select-fire airgun, the Crosman DPMS SBR provides the look, feel and manual of arms of a short-barreled, center-fire, AR-15-pattern carbine—without the tax stamp. Making use of polymer receivers and a steel smoothbore barrel, the Crosman weighs in at 6 lbs., 3 ozs., and a six-position-adjustable buttstock allows its length to be set from 26.5" to 30.25" long. A flat-top receiver and quad-rail handguard allow for the mounting of optics and accessories, and a set of plastic flip-up sights ship with the gun. Powered by two 12-gram CO2 canisters concealed within its 25-round detachable box magazine, the DPMS SBR, when in full-automatic mode, is capable of discharging its entire payload of .177 cal. BBs in little more than a second—at speeds up to 430 f.p.s. Price: $199. crosman.com.
