Rely on the King Arms Colt M4 CQB-R gas blowback airsoft rifle to dish out the necessary firepower needed to advance your squad successfully on the battlefield. This realistic replica is built to the same size, specs & features of a real Colt M4 right down to the official engraved logos on the receiver! The M4 CQB-R is a mix of metal & ABS plastic components and has a robust weight that won't be a hassle to carry for extended airsoft skirmishes. The rifle features a quad Weaver/picatinny tactical rail for mounting shooting accessories of your choice, a 50 rd magazine and a shot velocity of 320-340 fps (using .20g BBs). The rear sight can also be removed from the monolithic top Weaver/Picatinny rail for mounting a riflescope of your choice for enhanced accuracy. Attach a gun sling on the sling mounts for easy carrying in the battlefield!
