Umarex Strike Force Features The Umarex USA Strike Force is powered by two 12 gram CO2 cartridges stored in the buffer tube of its adjustable lightweight tactical stock keeping the design compact and easy to handle. A three position thumb operated switch located above the grip lets shooters select between safe semi automatic and fully automatic fun switch modes to match the moment. Firing steel BBs at 450 feet per second the Strike Force delivers enough energy for engaging targets in the backyard or at a range session. The 10 inch profile barrel keeps the overall footprint short and maneuverable matching the look of a modern sporting rifle style platform. A 30 round drop free magazine speeds up reloads between strings of fire while the removable flip up front and rear iron sights provide a fast backup aiming option. The full length Picatinny rail on top of the receiver accepts a red dot reflex sight or scope for shooters who want a more precise aiming solution. An M-LOK slot equipped handguard allows the addition of lights grips or other accessories to further customize the build. Shipping with one magazine a BB speedloader and interchangeable grips in three sizes the Strike Force gives shooters everything needed for immediate full auto BB gun action right out of the box.
