The RISE Armament Lower Parts Kit includes the working components of an AR-15 lower receiver, minus the trigger. This 20-piece kit is compatible with mil-spec AR-15s and is built for assembly with quality parts that withstand continuous shooting.
Most mil-spec parts in the kit are made from industry-standard 8620 steel, a nickel-chromium-molybdenum alloy with 0.2 percent carbon for toughness and strength. The safety detent pin and takedown/pivot pin detents are yellow zinc. Many parts use a black phosphate finish that adds an inert layer for corrosion protection.
