The Maruzen MP5K Charger is a fun little package, providing gas blowback thrills in an MP5K, with semi and full-auto modes. It comes fitted with an extendable stock and an RIS rail system to mount optics or lasers, should you require. Most of it is made of ABS plastic, although the front sight, magazine and flash hider are made from metal.
Simply fill the mags with gas (and BBs) and you're ready to shoot! No need to charge batteries. The performance is a modest 230fps, although the real fun comes from the blowback you get in full-auto mode. Feel the feedback as you rattle off the 30 gas powered rounds. Lots of fun indeed!
