The flat 2 stage 2lb/2lb trigger is imho the best all around trigger for ar's on the market. - CMC Triggers AR-15/AR-10 Match Grade 2-Stage Trigger Group

I put the 2 stage 2lb./2lb. in my BCM 16" Mk2 middy build and have been impressed ringing steel at 830 yards as well as shooting steel standing at 50-75 yards with great feel and ability for rapid follow up shots. The fixed boot at the bottom is great, especially while wearing gloves to help ensure the same finger placement for each shot. That is HUGE and that is repeatability you can depend on. No adjustable "boot" or "shoe" here like some of my other competition triggers.
As a former SOF guy myself, this is my #1 rated trigger. PERIOD.
I'm buying another of these to replace the Geiselle SD3G trigger that came standard on my DDM4V11Pro. I've had problems with unintentional double taps with that trigger and some feeding/ejecting issues as well that i blame on that trigger.
The Geissele SSA-E is awesome as is their Super SCAR trigger... and i do love Hyperfire triggers too.... but again... my favorite, best all around trigger that i could and would trust in combat would be the flat, CMC 2 stage 2lb/2lb trigger.
