kwa usp problem

Sep 29, 2005 12:30am
the problem that i am having is the first shot is fine. the next shot, the slide will cycle and the bb will roll out of the barrel. cleaned it and it still has a problem. even turned the hop-up off. don't know??? any ideas or anyone with the same problem? a few times the first shot was ok and the next four shots the bb stayed in the barrel until i tipped it down ward. the 4 bbs just rolled out.

are you talking about the p8? If so, there is a screw at the bottom of the barrel assembly that sometimes loosens, try tightening just a tad, and maybe some weakened loc-tite to cure future ailments...

tried it. broke it down and cleaned it. still has the same problem. thinking the bb is traveling to far into the barrel during the cycle and in front of the cylinder there is a metal shaft that is spring loaded. when depressed by the bb, it opens the valve to propel the bb. thinking the bb is moving too far foward and the valve isn't opening. it will blow back and cycle fine without bbs. hum???? maybe i'll break it down all the way and really clean it up. if not, i'll take it to the guys at aex for a 'looks-ie" thanks for the tip though.

i heard about something like this happening to kwa p8's. if its what i'm thinking there's an oring inside the blowback chamber that might have fallen out. theres some posts on airsoftretreat/airsoftplayers about it. i think aex might be able to fix it.
What's a signature?
