LMT 5.56mm Lower Parts Kit, No Trigger Group

The LMT 5.56mm Lower Parts Kit, No Trigger Group (LMT part no. R-LM556LPKL) supplies the small internal components needed to finish an AR15 stripped lower receiver, minus the trigger group, for shooters who plan to install their own drop-in or aftermarket trigger. This version includes the springs, pins, detents, and other hardware that are easy to lose or overlook during a build. LMT builds the kit to mil-spec dimensions so every part fits a standard AR15 lower without modification. It’s a practical option for builders who already have a trigger picked out and don’t need a duplicate mil-spec unit.
