Gun Building, Modifications & Repairs
Hey guys! I am getting back into airsoft after a 2 year break, and i'm getting into teching now. I'm attempting to fix up an old M4 i have before i sell it. I am attempting to remove the upper RIS from the gun, and have had no luck. It is a JG/Matrix M4-16 Zombie KIller. THe RIS is rather odd...
