My LEO son just had to qualify with his Bushmaster AR-15 that I had installed a Geissele SSA trigger in. Somewhere just over 300 rounds into the day the trigger would not return to battery. Upon inspection my son found that the coil spring that resets the trigger was in a "bind" and would not allow the sear to catch the hammer.

I put the Bushmaster trigger back into the rifle since he had qualified with it for years without any trouble.

Right now I think a Geissele is fine for target shoots or a day in the varmint field but I would not have my life depend on one. Now I know many thousands of these triggers are in service and work fine, and mine is a rarity, but once you have lost confidence in something it is hard to return.

I will be sending it back to Geissele for their inspection and comment.
