I'm no expert on ar aftermarket triggers(never used one other than this) so take this for what its worth. Shot my rock river arms trigger on sunday and it was great. Faster firing, easier to shoot. I went with it because of its price and because it has no set screws so its good to go for combat. It was a trouble free drop in job. Went in a bushmaster. Got it from John Holliger (gasgunner) and he was fast with delivery.
