Hey i just picked up a couple king arms gbb m4 mags for my kjw m4 gbb and they wont fit in the gun, but when i take out the back pin and lift up the top reciever and then put a mag in it will click into place, but when i try to put the top reciever back down it just bumps into the feeding lip on the mag. I was thinking of sanding down the front part where the feeding lips bumping into but i don't know if that would screw things on my gun up. someone please help!
