Rise Armament AR15 Lower Parts Kit

Rise Armament AR15 Lower Parts Kit

The RISE Armament 20-piece AR-15 Lower Parts Kit includes all the necessary components for assembling a lower receiver, excluding the trigger. It’s designed to work seamlessly with mil-spec AR-15s.

Most of the parts in this kit are constructed from 8620 steel, a robust alloy comprised of nickel, chromium, molybdenum, and 0.2 percent carbon. This steel is durable and tough, making it ideal for the kit’s components. The Safety Detent Pin and Takedown/Pivot Pin Detents are also made from yellow zinc, ensuring they can withstand continuous shooting without wearing out quickly.

The RISE Lower Parts Kit parts are also treated with a black phosphate finish. This finish forms a protective layer on the steel, preventing corrosion and extending the kit’s lifespan, even during extended shooting sessions.
