The APS M4 Gaurdian Combat Rifle incorporates a revolutionary design that allows players to quickly change their spring for a higher or lower FPS. Externally, the gun features a full metal upper and lower receiver, RIS rail system, metal barrel, and buffertube. The tactical M4 crane stock is fully extendable and can be retracted for a low profile during CQB operations. The ergonomic pistol grip is designed to give the user the best possible handling while reducing bulkiness. The flip-up iron sights can be folded to accommodate optics or scopes. Internally, the gun comes stock with high-speed performance gear set, ball bearing spring guide, and reinforced piston, cylinder, & tappet plate. The patented electric blowback adds to the realism of this airsoft rifle and provides users with an authentic feel. Performance, durability, and realism is hard to come by. APS has provided all three in one package, whether you're just beginning to dive into the airsoft world or are a seasoned veteran.
