Santan Stt-15 5.56 30-Round Carbine

The San Tan Tactical STT-15 5.56 NATO 30-round carbine is purpose-built for operators demanding a reliable, compact platform for tactical, defensive, and training applications. Designed for law enforcement, military personnel, and serious civilian shooters, this semi-automatic rifle delivers proven performance in a mission-ready package. The 7.5-inch barrel configuration balances velocity retention with portability, making it ideal for vehicle operations, close-quarters engagement, and dynamic entry scenarios where maneuverability matters.

Built on a direct-impingement system, the STT-15 uses proven 5.56 NATO ballistics with a 30-round capacity to maximize tactical flexibility and sustained rate of fire. San Tan Tactical's engineering prioritizes reliability under sustained operations—critical in duty and patrol environments where malfunction tolerance is zero. The short barrel length (7.5 inches) reduces overall length without sacrificing chamber pressure or velocity consistency, while the semi-automatic action ensures compliance with civilian regulations. At 10.63 lbs, the rifle maintains a lightweight profile suitable for extended carry and rapid target acquisition.

This carbine is purpose-matched for operators running duty or home-defense setups who require a compact, semi-automatic 5.56 platform. The 30-round magazine capacity pairs seamlessly with standard AR-pattern accessories, allowing integration into existing load-outs without additional logistical burden. Users benefit from the 7.5-inch barrel's compatibility with standard 5.56 suppressors and muzzle devices, enabling sound reduction or recoil mitigation when mission parameters require. Whether configured for patrol, training, or civilian self-defense, the San Tan Tactical STT-15 delivers the accuracy and dependability operators have trusted in the field.
