Non-NFA - ATF ApprovedUSM4 TAC-CON 3MR trigger
The 3MR is a drop-in 3-mode fire control system with Safe, Semi-Automatic, and Tac-Con™’s patented 3rd Mode. The 3rd mode has a positive reset that dramatically reduces the split times between shots. The positive reset characteristic is achieved by transferring the force from the bolt carrier through the trigger assembly to assist the trigger back onto the front sear. As a result, this gives the firearm the fastest reset possible. Both semi and 3rd mode positions exhibit a non-adjustable 4.5 pound trigger pull weight.
USM4 lower receivers are machined from 7075-T6 billet aluminum, bead blasted then hard anodized.
