Hello everyone, first time poster here. I recently bought a paintball gun from a friend of a friend, and I'm trying to identify the make and model. I don't see any identification marks aside from a single star on the grip, though I'm not sure whether the grips are aftermarket or not, and google doesn't bring anything up. The only other mark that I can see is what appears to be a homemade serial number. It looks like an M4 carbine, and that's about all I know about it.
Since the max picture size is so small for this forum, I uploaded a couple of pictures of the marker to imgur.

Any help in identifying this thing would be greatly appreciated.
