The DPMS AR-15 B5 Systems Lower Build Kit packs the standard necessities to finish a DPMS stripped lower into one box, so you are not hunting down parts one at a time. Its heart is the Panther Polished Trigger (PPT) lower parts kit, which swaps the standard fire control group for a single-stage, target-style group. The contact surfaces are polished and carry an electroless nickel coating, which is the upgrade over the standard group. The fire control group covers the AR-15 hammer, trigger, disconnector, their springs, and the trigger and hammer pins.

For the rear of the lower, the kit includes a mil-spec diameter 6-position buffer tube assembly with the buffer, buffer spring, castle nut, latch plate, and buffer retainer detent and spring, so the stock can be set at 6 positions. The B5 Bravo stock mounts on that tube, and a B5 pistol grip and B5 trigger guard come in the box to round out the lower. A takedown and pivot pin assembly is included with 3 takedown springs and 3 takedown detents, so the pins you need to join the upper and lower are covered. The bolt catch assembly adds the bolt catch, detent, detent spring and roll pin.
