The Falcon AR Lower Parts Kit - Pins & Springs are a premium quality lower parts kit for the AR-15 platform, built to mil-spec dimensions but with higher quality materials and finishes. Every component is precision machined from 303 stainless steel and finished with a Tuffride coating a ferritic nitrocarburizing treatment that dramatically increases surface hardness, wear resistance, and corrosion protection, ensuring these parts outlast standard mil-spec alternatives in even the most demanding conditions. Compression springs are manufactured from M3 steel for consistent, reliable performance across thousands of cycles.
Whether you're building a new lower or replacing worn components, the Falcon AR Lower Parts Kit delivers the quality and longevity that discerning builders demand.
