"Hey, I received this barrel extension/mock suppressor recently, and MAN is it great. It has an extremely realistic weight and feel/look to it. I originally bought it b4 i bought an extended tightbore for my m4. But it was well worth it. At the time the back end of my m4 was a bit too heavy compared to front. Now, thanks to this silencer it is perfectly even, the gun sounds cleaner and less like metal clanking together. And on top of all that, it is a great OD green color, and it hides my barrel extension.
