| I took my newly built 16" out to the range yesterday for its 1st test shooting. I loaded up my 2 ( I know I need more) 30 round pmags. One is a used gen1 that came with my stripped lower and the other is a new 2nd gen window. I load the 2nd gen window, chamber a round. Fire, empty case comes out but the next round gets stuck trying to feed. Clear, repeat. Same thing ftf. I did this five times with the same results. WTF 1st time out with my new gun and its already giving me problems. So I drop the mag, grab the old beat up 1st gen. Chamber, bang bang bang. No problems at all. The gun ran as it should. I fired the 30 rounds, reloaded fired 30 more. No problems. Hmm might be a mag problem. I unload the new 2ng gen. Reload it and the same thing. 1st shot is fine, then ftf. Did I get a bad 2nd gen mag or does it need to be broken in, or am I doing something wrong. Any help, thoughts, suggestions? |
Chambers every time

Quoted:
Check for mag movement front to rear in the receiver, i had one mag in one particular lower that if i pulled back on the mag while trying to chamber a round it would jam every time. If I pushed forward on it, no problems. Try this. If it makes a difference, try screwing in teh mag catch in 1 turn. |
