KJW m9 bb dropping to the ground
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.
