I put one on a Defiance Machine receiver for a precision rifle, and something was wrong with it as the bolt always felt as if it was dragging on something, as if there was some kind of grit in the rifle's raceways. No matter how I cleaned things, the rough feeling remained. Trigger pull weight was fine, and the trigger and safety both operated properly. I replaced it with a Timney trigger and the problem disappeared. I'll let folks draw their own conclusions.
ETA: Other triggers I have used were Jard, Canjar, Rock River, JP, Larue,and have had triggers for M1-A's, Garands and an HK91, worked over by Williams trigger specialties, Cylinder and slide, Wilson, and other's I can't even remember right now...so I have tried a few different triggers on semi-auto handguns, various rifles, and revolvers. I did think the Jard trigger was a little too light for my preferences on an AR15, but it worked properly...it was just hard to keep it from touching off a second shot...it didn't double, it was actually a very sensitive trigger prone to bump firing.
