I have a Giessele G2S trigger in a 10.5" SBR that about 30% of the time will not reset.
Hammer spring legs on top of trigger pin, Trigger spring legs oriented to the front. Supplied grease used as directed.
Round fires, ejects, re-chambers a fresh round, trigger stays to the rear, no reset click.
Sometimes I can push it forward with my finger, sometimes I can't move the trigger.
Safety on, safety off, pull the trigger........nothing.
Drop mag, clear the chamber, open the upper, yep, trigger is set back past the sear??
Pull trigger, and hammer will fall.
Reload, chamber, fire 5 or 6 rounds.....trigger doesn't reset. Safety on, safety off, push trigger forward, won't move. manipulate the safety on and off, nothing, manipulate the hammer, nothing. look at it for a few second *tick* trigger rests as I am looking at it....
I am wondering if my recoil spring is too light. (I installed a lighter weight spring and standard buffer) But I have an adjustable gas block and I've tuned it pretty low.
Brass flies about 2-4 feet to the two O'clock.
Trigger works perfectly when cycling by hand.
Any tips or suggestions?
I'm going to change the recoil spring back to a standard and bring different weight buffers tomorrow and see what happens then.
