DPMS Lower Parts Kit Features The DPMS Lower Parts Kit supplies everything needed to complete an AR-15 lower aside from the fire control group grip and stock giving builders a focused solution rather than a redundant full kit. The takedown and pivot pin assembly includes the takedown pin pivot pin two takedown springs and two takedown detents allowing the upper and lower to separate smoothly for cleaning and maintenance. The bolt catch assembly with its detent detent spring and roll pin locks the bolt open on an empty magazine for safe and efficient reloads. The magazine catch assembly and safety selector assembly round out the core functional components giving the rifle reliable magazine retention and positive safe-to-fire selector operation. An enhanced polymer trigger guard along with its roll pin and set screw provides a durable and comfortable surface compared to older stamped metal designs and the included hex key means no additional tools are required for final assembly. With 22 total pieces in black finish this kit suits builders finishing their first AR-15 lower as well as experienced owners keeping a spare parts kit on hand for field repairs. Because it leaves out the fire control group grip and stock shooters can pair it with their preferred trigger and furniture without paying for parts they will not use. The DPMS Lower Parts Kit is a practical affordable way to keep an AR-15 build moving forward.
