Not the best, but not the worst - HIPERFIRE Enhanced Duty Trigger AR Fire-Control Group w/Curved Trigger, 4.5/5.5lb Pull Weight

I thought it would be better than what it is. I thought the bottom of the trigger and the bottom of the hammer will be polished for a even smoother trigger pull. It is kind of gritty on trigger reset, but the reset is very short also their is No take-up. Trigger pull weight feels a lot heavier than 4 1/2 as they have advertise, but way lighter then mill spec. The hammer is very hard hitting, no worries here about light primer strikes. It hits harder then mill spec hammer. It's a good in-between trigger better than mil-spec but no competitions trigger.
