Re: m15a4 misfeeding

Would help to have some more information.

Does the motor and gear box cylce to shoot 2 or 3 bb's or do they just dribble out after one cycle?

Re: m15a4 misfeeding

sorry gear box works normaly just every other cycle its spiting 2to 3 bbs at a time

there not just falling out of the end

Re: m15a4 misfeeding

if i remember correct you had the gb apart not long ago for a spring down grade ? did you put the Ar latch back in correct ? and is there a sort of funny noise during end of the cycle ?
only asking as i have a arl spring break on me in a ca m15 and that would double feed becouse the spring pushed the gears back meaning the nozzel loaded twice

Re: m15a4 misfeeding

hmm ok worth a try , ok wip the barrel out and look for damage on the hop rubbers you could even push the feed tube direct on to a loaded mag and see if only 1 gets pushed up there or if the 2-3 do , while the upper half is off hook it to a battery and see how the nozzel moves ( it might be damaged )

even better use the hop and barrel from your other m15

Re: m15a4 misfeeding

Re: m15a4 misfeeding

Re: m15a4 misfeeding

follow up

i had the upper off and connected up the battery and i would say the air nozzle is not returning fully on semi like its sticking ???

auto works a treat

Re: m15a4 misfeeding

have a look at the tappet plate make sure the spring is in good order and that it runs free within the gearbox also is the air nozzle running free on the cyl head nozzle

Re: m15a4 misfeeding

sounds more like over run, its worth going into the gearbox and giving it a service. maybe replace the cut off lever for the hell of it.
