this is an aluminium piston;
anyone knows why it broke at the first tooth like that ?
the battery I used was 10.8V / 5000 mAh, the spring is under 350 fps.
does it mean that the piston breaks when the sector gear catches it ?
1.I suffered some misfeed the mag before the failure, but not on the mag during the failure, that was spitting BBs like there was no tomorrow.
2.When I took it apart there were two bbs jammed in the barrel.
3.BBs are Bastard tracers.
do you think a plastic piston will explode into a million pieces if I try it on this config ?
is that clearly jamming-related?
thx all
