DPMS DR10 Upgrade Kit Features The Dpms Panther Arms DR10 Upgrade Kit is built around a simple problem: an AR-15 lower parts kit will not directly fit an AR-10 lower without a handful of larger-format components. This kit supplies exactly those parts the bolt catch magazine catch takedown pin and pivot pin sized correctly for the AR-10 platform. Machined from black aluminum the four pieces are built to drop into a standard AR-10 lower receiver alongside the rest of an AR-15 lower parts kit. At 4 inches of combined length across the components the kit is compact and easy to keep on hand for a build. For builders who already own an AR-15 lower parts kit this upgrade kit avoids the expense of buying a complete separate AR-10 specific parts kit just to cover a few dimensionally different components. The black finish matches standard AR-10 hardware so the completed lower looks factory-correct once assembled. This approach is a practical budget-conscious way to finish an AR-10 build using parts already on the bench. For anyone converting an AR-15 parts kit for AR-10 use the Dpms DR10 Upgrade Kit is available for sale at GrabAGun.
