Well I installed the RRA triggers on two AR's. All I can say is outstanding. I also put a PSA "enhanced" trigger on another lower. The stock trigger was like three miles of creep, potholes and a curve. The Enhanced trigger made for a smooth letoff anyway and not too heavy as I replaced the hammer spring also. I really like the RRA triggers though, makes shooting consistent small groups much easier.
The PSA EPT? I have a couple and think they are decent, well, they're better than standard forsure. Still undecided on the RRA, Larue and PSA two-stage triggers I am supposed to be testing.... Sidetracked. I have used the Larue the most and do like it.
Guess I have the RRA NM, not Varmint.
Did anyone try the PSA drop in from the op?
