Santan Stt-15 5.56 10.5 30rd Tgr Stp

The San Tan Tactical STT-15 5.56 10.5" 30rd TGR STP is a semi-automatic modern sporting rifle engineered for operators who demand compact profile without sacrificing reliability. Purpose-built for tactical applications, home defense, and precision shooting in confined spaces, this platform delivers genuine combat capability in a package that excels in vehicle operations, close-quarters scenarios, and dynamic tactical environments where maneuverability outweighs extended-range performance.

The 10.5-inch barrel strikes an optimal balance between velocity retention and handling agility, generating sufficient muzzle energy for intermediate-distance engagements while maintaining a compact overall length that reduces sight radius and handling time. The trigger group (TGR) design provides crisp, repeatable single-stage or two-stage geometry depending on configuration, critical for controlled fire and shot placement. The integrated step design enhances ergonomics and aids in weapon manipulation, while the 30-round magazine capacity ensures adequate ammunition supply for duty use, training, and competition without the footprint penalty of extended-capacity alternatives. Weighing 9.69 pounds, the STT-15 remains balanced and portable—essential for extended patrol or tactical operations where shooter fatigue directly impacts accuracy and response time.

Law enforcement, military personnel, and serious civilian operators benefit most from this platform's proven reliability and modularity. The 5.56 NATO chambering ensures ammunition commonality with issued duty rounds and widespread availability across the supply chain. Installation and maintenance follow standard AR-15 protocols, allowing shooters with baseline platform knowledge to execute field-stripping, cleaning, and component swaps without specialized tools or training. Compatible with standard .223 Remington and 5.56 NATO ammunition, the STT-15 performs reliably across military and commercial ammunition grades, making it adaptable to evolving mission requirements or emergency resupply scenarios.
