This is a great upgrade to your standard mil-spec trigger group. Clean break , reduces trigger pull weight, short reset. The roller seems to make your trigger pull more straight back improving accuracy. I almost like this trigger better than my 2 stage match triggers. Be sure to use the red hammer spring if you plan on shooting .556, military, or foreign made ammunition. The yellow hammer spring will give you some lite primer strikes on those types of ammo. But if you are shooting regular .223 brand ammo, such as Hornady, Winchester, Federal then the yellow hammer spring does fine. All in all I wouldnt mind having these on all my rifles.
