I found this gun on an airsoft website called shortyusa.com. The website is really good because on most of there guns they have multiple views of the weapons. The MOD4 CQB is a light, agile assault rifle. At only 25 inches long it can be maneuvered around corners easier than its full sized M4 counterpart but still has the same feel and function. It's barrel makes it only slightly longer than an MP5. I pulled a lot of my ideas from Py Brick's hk416 and Marco P's M4A1. Also, Py Brick don't worry, I still plan on buying your stock because it is way better.
