San Tan Tactical’s STT-15 is a .223 Rem/5.56 NATO rifle built on a 7075 T6 pillar billet receiver machined from aerospace-grade aluminum. The 10.5-inch barrel is paired with a 30-round capacity magazine and full ambidextrous controls for either-hand operation.
The compact barrel length and standard-capacity magazine layout strike a practical balance between mobility and sustained shooting. The billet construction and ambidextrous ergonomics ensure consistent mechanical function and straightforward handling across different shooting disciplines. Made in the U.S.A., all STT products are backed by a Lifetime Warranty.
