Features
It has a mock suppressor that slides on and off of the actual barrel, On this suppressor is a 45 degree grip frame with mounts for a scope and laser.
Testing
I brought it outside and fired it twice once at 10psi to make sure it worked and again at 30psi, then my bike pump broke and the needle on the bike pump gauge snapped off, stupid Chinese made pump.
