The 2011 Version of the INOKATSU M4A1 SOPMOD is extremely well made and put together with pinpoint precision, making the INOKATSU extremely robust. The entire gun is SOLID with no wobbles and shakes. It feels like a real gun when you pick it up. Featuring a weight adjustable bolt carrier, the M4 kicks like a 9mm real steel weapon every time you pull the trigger with the weight installed (kick is just as strong as previous version Inokatsu M4). On the semi-automatic firing mode, the INOKATSU M4 SOPMOD is able to completely fire off all 50rds from its magazine. But if you are a skirmisher and want a faster rate of fire and don't care about the recoil as much, remove the weight from the bolt and the M4 can easily finish 50 rounds in full auto. To obtain this performance while maintaining a VERY strong recoil kick, Inokatsu had to dial down the power from the originally planned 460fps to approximately 400fps which is still more than enough. If power is important to you, you can still increase the FPS by installing a precision barrel.

With this version, INOKATSU has improved upon their previous 2009 version M4 GBB designs with an improved bolt for greater durability and more stable performance. The upper and lower receivers are also more refined with an improved fit and finish (tighter seam lines between the upper and lower receiver). This is a direct improvement based on feedback and discussion between customers, Redwolf and Inokatsu. All improvement made are in an effort to maintain Inokatsus premium dominance over other GBB rifles for realism, quality, performance and durability.
