cheap ol DPMS parts kit with the junkyard genius trigger job. Mil spec trigger breaks right above 3# with no creep at all.
i have the junkyard trigger job in my ar, it's nice but make sure you lock tight it. I had some issues with it first I had it screwed in too far causing issues (combined with too heavy of a hammer) second issue I had was I didn't lock tight the set screw and it worked its way up while firing the rifle causing the trigger not to reset with out pushing it forward to force it to reset, and it would not engage the safety.
