having the hardest of time removing the plastic body from the chassis of this atlas mp15 (chicago nw) i have. any suggestions? my gp9 slips off super easy (undec version)
Try using toothpicks or something similar to spread the shell just a tiny bit. Once one end starts to come loose you should be able to work the other end off without too much difficulty. After it's apart, grind down the mounting bumps on the frame to make it easier next time.
