The Umarex Steel Force air rifle is a clone of a short-barreled AR that operates with the use of two standard CO2 cartridges and fires steel .177 caliber BBs from a 300-round reservoir. The Umarex Steel Force is capable of both semi-automatic fire and six-round bursts.

In semi-automatic you get the most power for each shot, and the BBs exit the short 7.5-inch barrel at 430 feet per second. This gun has a flattop upper and features accessory rails on the bottom and right side of the handguard. It has similar controls to a standard AR and features a collapsible stock.
