Great trigger but setup was tricky. - OpticsPlanet Exclusive RISE Armament RA-434 High Performance Trigger

When I first installed the RA-434 trigger, I also installed KNS anti-walk pins too (not included). First 50 Rounds of 5.56 ball ammo I was amazed how smooth and light the trigger was. Then it started acting up. Reset was non existent and resulted in hammer follow. Long story short, the set screws that lock the unit in with pressure on the trigger and hammer pins was too tight. I loosened them and still no joy. I was about to give up until I adjusted the screws on more time, with the screws just barley with a hint of tension against the receiver. And it worked. Range tested with 100 more rounds of 5.56 with no problem. So do not overtighten the setscrews like the instructions stated, but also not too loose.
