Double firing in semi auto

Hughmann

As title states, im having a double fires in semi. Almost similar to a binary (one shot on pull and one on release) . In super safe i have no issues as far as i can tell. I’ve tried 1) new disconnector and spring, problem remained 2) new SS cut trigger, problem remained 3) factory selector with SS cut trigger, no issues. Have not tried a new SS yet but if i have order one to i have to. Any input is appreciated. Gun is a wraithworks warscorp9.

Hughmann I would try a different hammer first, or even another lower, the fcg pin holes may be worn/out of spec.

undeadchew tried a different hammer and issue still persists. I’ll try moving it to a different lower next although it’ll have to be an ar15, which i dont think should make a difference right?

I don't know exactly what your problem is but I had the same symptom due to a walking trigger pin in my SL15. Just ensuring the pin was installed properly fixed my issue

Patrick noted, ill keep my eyes on the pins next time i shoot, but i havent noticed them walking before

Hughmann Should be no difference between lowers if they are both in spec.
One last thing to check that crossed my mind is if the disconnector spring is fat side bottom down.

undeadchew havent gotten around to trying a new lower yet, but i tried another new disconnector spring which solved the problems in semi. However now i lost super safe(2-3 rounds then light strike). Im thinking that whatever issue was causing the double fires in semi was assisting in SS running reliably.
