I just bought this gun like 4 hrs ago shot great it was a dream as its my first GBB, I painted the lower receiver black, I did this by disassembling the whole guns lower half painting only the plastic parts no metal at all. On a side note it runs on c02(i like to practice in my room sometimes.

Thing is i think the problem may be from me reassembling the gun. When i shoot it, the gun locks up to an open chamber the stopper does not even stop it its just feels like the upper half is grinding w/ the lower half( i have to push the slide forward to get it to re-a-line) it keeps locking no matter how i keep putting it back together. But it doesn't seem to lock up when i cock the gun though, so it has to have something to do with the force of the blow back ill show pics of it stuck in a bit.

I know painting it could have caused the problem but when i check it the upper part and other moving parts dont seem to touch the lower plastic apart form the middle metal part.

Any help would be appreciated
Thank you
