x-valve

[frontrunner]

why does my x-valve fire when i air it up? The push rod doesn't tuch the triger but it still pops a shot off. It does this no matter how many shims are in my ule (2 or 7). it also stick once in a while when i really get on it does anyone know why and how i can fix it any help would be nice.... thanks

its normal for a mag to fire once when gassing up. for the bolt stick, check that the field strip screw is tight enough (finger tight plus 1/4 turn is usu good), otherwise, tune the lvlX

this is another good reason to hold the trigger in while airing your marker up.
