The Umarex H&K G36K Blowback is a replica of the Heckler & Koch G36KE rifle. Originally manufactured by Ares, this AEG is licensed by Umarex and features official H&K markings. Built into the carrying handle is a 3 x magnification optic with a short Picatinny rail on top of it, for mounting of additional reddots . Receiver, handguard and stock are constructed out of nylon fiber polymer whereas the outerbarrel assembly is made of aluminium. The Umarex G36K can be taken apart very similarly to the original rifle and it also features a fake gas block and piston beneath the handguard. To make this AEG even more realistic it features a blowback system and a functional bolt catch mechanism for an easy hop-up access. Also easy to access is the spring, which can be changed without taking the gearbox apart, thanks to the quick change spring design. Included is a 470 rounds high capacity magazine.
