A Reliable GI Trigger with Ground Engagement Surfaces for a Smoother Pull

When it comes to the classic AR-15 trigger you typically see in off-the-shelf rifles, they can leave a lot to be desired.  The AT3 GI trigger solves the biggest issue with why phosphated trigger groups suck: the sear engagement surfaces.  This trigger group is longitudinally-ground, resulting in hardened, somewhat polished surfaces on the trigger and hammer.  Without the phosphate coating in the way, these surfaces end up giving you a smoother trigger pull, with all the reliability you can expect from a mil-spec trigger.  Around a 6 pound pull weight, and strength to get reliable strikes on the primer every time.
