RISE Armament’s AR-15 Lower Parts Kit is a must have for anyone building a custom AR platform, or who want to optimize an existing AR. The majority of the parts in this kit are made from industry-standard 8620 steel – a full-up alloy of nickel, chromium, molybdenum, with 0.2 percent carbon. This gives these parts incredible strength and durability for a lifetime of reliable service. The parts are also given a black phosphate finish, which deposits an inert layer on top of the steel to prevent the corrosion reaction from reaching the steel.
