The San Tan Tactical STT-15 Billet Lower Receiver is a precision-machined component designed for serious AR-15 builders and law enforcement armories seeking uncompromising reliability. This billet aluminum lower receiver serves as the regulated firearm foundation for modern sporting rifle platforms, requiring proper FFL licensing for transfer and possession.
Built to exacting tolerances, the STT-15 is engineered for shooters who demand consistency across thousands of rounds and demanding operational environments. Machined from 7075-T6 billet aluminum, the San Tan Tactical lower receiver exhibits superior structural rigidity compared to forged variants, reducing tolerance stack and enhancing mechanical accuracy over extended shooting cycles. The precision pocket geometry ensures tight, consistent headspacing when mated with quality upper receivers and bolt carrier group assemblies.
Law enforcement armorers, competitive shooters, and precision rifle builders benefit most from the San Tan Tactical STT-15's dimensional consistency and long-term durability. Installation requires standard AR-15 assembly tools and familiarity with lower receiver completion, ensuring a straightforward process for builders.
