Our selection includes lower receiver components, springs, pins, controls, takedown pins, magazine catches, bolt catches, safety selectors, and other essential parts for custom builds and replacement projects. Designed for compatibility with many DPMS-style AR-10 platforms, these components help ensure reliable function and long-lasting performance.

Are AR-15 and AR-10 lower parts interchangeable?

Some AR-15 and AR-10 lower parts may be interchangeable, but many are not. Certain components such as pistol grips, trigger assemblies, safety selectors, and some springs or detents may share AR-15 specifications depending on the platform. However, AR-10/LR-308 takedown pins, pivot pins, bolt catches, magazine catches, buffer components, and other parts can differ by receiver pattern and manufacturer. Always verify that each lower component is compatible with your specific large-frame receiver before purchasing.
