BBs slide out of barrel

[Castle]

Gun: KJW Glock 23 GBB

When I initially pull the slide back all the way and release to chamber the first BB, everything is fine. However, after the first BB is fired and the slide blows back, the 2nd round rolls right out of the barrel.

Any suggestions? If it helps, all the parts are stock.

Thanks in advance guys.

have you turned the hop up all the way off? Many stock guns don't have enough retention at the hop up rubber to keep the bb from rolling out if the hop up is turned off.

Best of luck.

+1... or a worn out rubber could also do that....

After fiddling with the hop up (no idea whether I was turning it up or down), I haven't had a BB fall out yet. *knocks on wood*

Thanks for the help
