Santan Stt-15 5.56 16" 30-Round Threaded Barrel Rifle

The San Tan Tactical STT-15 5.56 16" 30-Round Threaded Barrel Rifle is a purpose-built platform designed for shooters who demand reliability without compromise. Chambered in 5.56 NATO, this rifle is engineered for law enforcement, military personnel, and serious civilian shooters who require a compact, versatile carbine capable of delivering consistent performance in demanding environments.

The 16-inch barrel strikes an optimal balance between velocity retention, handling, and accuracy, making it suitable for tactical training and duty use. The threaded barrel design (1/2x28) enables rapid integration of suppressors, flash hiders, or muzzle devices without requiring gunsmithing, a critical advantage in field conditions where accessory modularity saves time and reduces dependency on specialized tools.

At 10.63 pounds, the rifle maintains a manageable weight profile that reduces shooter fatigue during prolonged operations without sacrificing structural integrity or recoil management characteristics inherent to the 5.56 platform. This rifle benefits operators and marksmen who prioritize quick-handling performance in confined spaces, such as vehicle operations or close-quarters tactical scenarios.
