KSC G19 bb's Dropping Out of barrel
 

Hi there, I read about a similar problem some time ago and tried searching the forums for info but couldn't find anything (maybe it was on another site)...So here goes.

When I fire, instead of shooting the bb out with a high velocity like it should, the bb just drops out of the inner barrel. The blowback seems fine, its just that the bb's do not have enough force to propel them out of the inner barrel with some power. I tried turning the hop-up all the way down because i thought this may be stopping the bb's from going anywhere but the same thing still happens.

Any ideas appreciated!

Probably has to do with the internal gas parts, and the valve inside the blowback unit.

Check parts #24 and #25. The head of the rocket valve should be pushed up against the pin (part #26) by the spring (part #25).

I replaced the rocket valve (part 24) with spare one that i had lying around and now it works fine. Its strange because the rocket valve i had in there before was metal too and wasn't broken or deformed.

Thanks for the help guys.

Good chance a double feed too. One BB rips out and the other drops out. Or, your hop up rubber is FUBAR.
