AR15 Lowers

AR-15 lower receivers are the legal and structural base of any AR build. At SanTan Reptiles & Firearms in Maricopa, AZ, we offer complete and stripped lowers in forged and billet configurations, ideal for custom rifle projects or replacements. Choose from mil-spec or enhanced models compatible with standard AR-15 uppers, triggers, and accessories. Whether you’re building a tactical AR rifle or a registered SBR, start with a durable lower from our selection. Add magazines, sights, and cleaning kits to complete your build.
