M9 GBBP Going "full auto"
Hi everyone.
I have a Jg M9 and recently put some upgrades in it including a 150% guarder spring set and a new guarder 'piston head'. Previous upgrades were an action army bearing spring guide and an action high flow valve. With the nee upgrades, the pistol shoots okay its first couple shots and all the sudden goes fully automatic. Sometimes it just goes full auto right on the first trigger pull on a new mag. With the stock recoil spring and trigger sping it shot without full auto problems. What could possibly be happening? The sears seem to be in good condition. On a side note thr gun has been sitting awhile before these nee upgrades. Thanks everyone.
