Very nice trigger - Timney Trigger Impact AR Trigger

Worked out perfectly in my PSA M4 carbine. Clean, crisp 3lb break and very short reset. No take-up or overtravel. Adjusting screws eliminate need for anti-walk pins. Set screws a little difficult to get past hammer spring, but not too bad. Make sure to put selector in before installing pins. I have Timney triggers in my Ruger M77 and Remington 700 also. Very happy with all of them. Highly recommend.
