For informational purposes only. This blowback-masterpiece features an all aluminum body (CNC finishing) unlike that of the WA (which has a lot of plastic parts due to restrictions in Japan) and they all look exactly like the real thing! The manufacturing process is the same as the real steel version which gives the Inokatsu M4 it's realistic finishing and color and is unfortunately the reason the gun has been banned in the US. Experts who have seen the gun say that parts such as the front sight and the markings on the receiver are almost indistinguishable from the real steel M4. Even the cocking lever has the same resistance when you pull back on it. The barrel and bolt are made from solid steel. This gun is very solid and heavy. Everything about this gun screams quality and realism, and if you want an all metal M4 with gas blowback, then you should seriously consider one of these. The parts are incredibly tough and resilient. In fact, this gun can handle Red Gas!, which gives a nice performance of 450+ fps. The piston is solid steel and the blowback on this is as equally solid, in fact blowback performance on the Ver 2 is a whopping 70% stronger than the Western Arms or the WE version! Emptying the mag will lock-back the bolt just like the real thing. Great attention has been paid to the details, for example, only when the gun is cocked does the safety lever go to safe mode. Other features include: collapsible stock and removable RIS covers.
