AR15's don't require break in to function properly.
This. I have built a half-dozen AR's (none gas piston) and none needed any breaking in to cycle the bolt properly and reset the trigger.
I would surmise the gas piston set up is your real issue. If the trigger is really not resetting, then buy replacement mil spec trigger parts for $30 or so and swap them out. If you still experience your issue, it's not the trigger.
IMO, it's not the trigger.
