KJW m9 bb dropping to the ground

Simon1234 · June 21st, 2007, 13:01

Hi, suddenly, when I coke a bb from the magazine, if I lower the front end of the gun the bb fall down. On regular shooting, one on two bb fall to the ground and leave me a blank shot. When I'm shoot the fastest I can, everything is good. What is broken? Thank you, by the way I have an high flow valve and home made enchanced recloi/hammer spring.

fix hop up or adjustable hop unit?

Most likely the hop-up rubber has just wore out, so when you pitch the barrel towards the ground, there is no resistance to hold the BB in place. Now this is assuming that the BB is just rolling out and the gun is not even fired. If its just rolling out when the gun is fired, then it can get into a whole maintenance issues.

It is an ajustable unit. The bb is just rolling out whitouth firing. In fact I can just let a bb roll in the barrel and fire after.

yep the rubber in the chamber is worn out. You'd have to get in touch with out of the importers that are around on ASC here to see if its possible to order replacements.

I removed the barrel and look at this rubber, I tried oiled it with silicon. Now sometimes it hold the bb the gun down, others times it doesn't. I'l try to find one ot order, thank you very much for the help
