San Tan Tactical STT-15 Ambi .223 Wylde 16" Rifle

The San Tan Tactical STT15 5.56 AR15 Rifle is meticulously crafted with matched, hand-finished pillar billet sets and a fully ambidextrous lower featuring three QD attachment points. Its upper receiver is precision-machined from a single solid 7075-T6 Certified Aerospace Aluminum block, ensuring concentric and perpendicular alignment for long-term accuracy. The rifle is equipped with a San Tan 5.56 barrel made from 41V50 vanadium steel, featuring a 1:7 twist, a ½-28 threaded end, and a dimpled design for optimal gas block retention. A CMC AR15 3.5lb Single Stage Flat Bow Trigger, known for its exceptional surface finish and precise dimensional control, provides a crisp and consistent trigger pull. Internally, the STT Enhanced Bolt Carrier Group, crafted from 9310 case-hardened steel and tested to 70,000 psi, includes three gas ports for improved suppressor performance and a black nitride finish with a staked gas key. Rounding out the rifle is the Midwest Industries® combat rail, which offers a full-length picatinny rail with M-LOK attachment points and additional QD sling mounts for enhanced customization.
