All San Tan Tactical STT-15 and 6ARC rifles are engineered from the ground up with one thing in mind. Reliability. Every part of the rifle has been thoughtfully curated to work in concert to deliver an attractive workhorse.The heart of our rifles is of course the flagship Pillar billet receiver set made of 7075 T6 aerospace grade aluminum featuring a full suite of ambidextrous controls including bolt releases and magazine releases.


This isn’t your standard AR receiver set — The Pillar billet receiver combo is the flagship product for STT. Our sets are milled from 7075 T6 aerospace grade aluminum on our state-of-the-art Mazak and Haas CNC machines. Everything from the flair in the magwell to the ambidextrous controls is designed with the shooter in mind.


Our approach to the AR-15 upper receiver is that it needs to stand out from the crowd of existing offerings while offering improvements and features not seen elsewhere. No more blocky, heavy, thick design that is CNC machined — We wanted to break that pattern. Our receivers are cut from a single billet 7075 -T651 aerospace grade aluminum.


The STT-15 was born out of a desire to develop a true ambidextrous AR-15 pattern weapon system, built to the tightest possible tolerances. The full suite of ambidextrous controls comes standard on all Pillar AMBI receiver sets and lowers and allows for standard manual of arms from both the right- and left-handed operation of the weapon.


The STT MLOK quick detach sling mount is a perfect solution for those looking to attach a rifle sling to an MLOK rail at their position of preference and The STT MLOK picatinny rails are perfect for those looking to add accessories to any MLOK rail such as lights, lasers, and grips. All mounting hardware is included and backed by our bombproof lifetime warranty.
