Systema have released their M4A1 MAX (M150 Cylinder). It's a full personal training weapon ready to go out of the box! It's a Full Die casted and high strength (ADC-21) metal unmarked body.
It has the same dimensions as the real steel version in all respects. They weigh the same and feel EXACTLY the same. Designed for police and military training use, Systema's M4-A1 airsoft rifle comes with a superior gearbox for greater reliability. Full metal body and components coupled with real steel spec stock, pistol grip, and foregrip makes the rifle very realistic in practical operations.
While Marui M16 magazines are in fact shorter than the real steel dimensions, Systema's PTWs comes with a 120 round magazine with exact same dimensions as the real thing. The extendable Crane stock which stores the factory recommended Systema 9.6V battery [SYS-AEG-NM16-ACC05] or even a 11.1v LiPo battery (change of connector required).

A efficient, high performance 7511 type motor
Highly robust Stainless steel cylinder case
A tapered inner barrel for additional accuracy
Revised and enlarged hop up roller for added shot stability
