San Tan Tactical’s STT15 5.56 AR15 Rifle is built with their true matched, hand finished pillar billet sets. The STT15 lower is fully ambidextrous and has three QD attachment points.
The upper is cut from a single solid 7075T6 Certified Aerospace Aluminum. The bore, receiver extension face, barrel nut threads and barrel extension surfaces are all machined in one operation ensuring that they are perfectly concentric and perpendicular to the barrel assembly. Our receiver serial number matched sets are hand ground for optimal fit, finish and long-term repeatable accuracy.
Adding to that the San Tan 5.56 barrel, machined from 41V50 vanadium steel with a 1:7 twist, treaded ½-28 and dimpled for gas block alignment and retention.
Built with the CMC AR15 3.5lb Single Stage Flat Bow Trigger. CMC Triggers is the original manufacturer of the Drop-in Trigger Group for the AR-15/10 rifle since 2003. CMC’s critical sear engagement surfaces have a proprietary machining process that renders superior surface finish and dimensional control. As compared to their competition, the techniques used to establish a 1-2 RMS surface finish as opposed to EDMing which leaves a pitty 32 RMS, compared to a mirror which is 0 RMS.
STT Enhanced Bolt Carrier Group – AR15 5.56 BCG rounds out the internals, STT's BCG is 9310 case hardened steel, magnetic particle tested, and proof tested to 70000 psi. It features three gas ports to bleed of excess gas encountered with suppressors, the full auto tail is enlarged and chamfered to allow for faster center up in the buffer tube and prevents carrier tilt. Finished in Black Multicam Cerakote with a steaked gas key.
