Triggertechs have never seen a round. All triggers are single stage. They came in some new guns i bought, and im a fan of the geissle Triggers at the moment in my ar platform rifles.The triggertech competition ar15 trigger is 3 pounds and crisp. Asking 140$ shipped. The Triggertech duty is 3.5#, asking 90$ shipped. The last one is the CMC 3.5# flatblade and asking 60$ shipped. The cmc has seen the range twice. When i bought it, it was sent back to cmc for some creep, and it was replaced by cmc. Will sell all 3 as a bundle for 210$ shipped in the lower 48.
