When inserted in a grenade launcher, and fired, it shoots all the BB's at once with a big blast, great for room clearing and suppressive fire. Features: Full metal and polymer construction. H&K style folding stock. 4 accessory rails. Sling mount. Built in fixed sights. Solid built. Detachable front-grip. Authentic markings. Uses any length 40 mm airsoft grenades.
