San Tan Tactical

San Tan Tactical is a premier name in high-performance AR platforms and components, building rifles and receivers that emphasize precision, reliability, and modern ergonomics. From the flagship STT-15 to purpose-built 6mm ARC rifles, every product reflects a background in aerospace and defense manufacturing focused on tight tolerances and consistent performance. Built around ambidextrous controls and billet construction, San Tan Tactical rifles and parts give serious shooters a refined, ready-to-run AR foundation backed by a lifetime warranty.

Precision AR Performance

San Tan Tactical designs its rifles and receivers for repeatable accuracy and predictable handling. Pillar billet receiver sets are cut from 7075-T6 aerospace-grade aluminum and matched as upper and lower pairs to keep play to a minimum for better consistency at distance. Carefully thermal-fit barrels and quality triggers help shooters take advantage of match ammunition and precision optics. The result is an AR system that can support sub-MOA accuracy in capable hands while maintaining dependable cycling.

Ambidextrous Tactical Versatility

Every STT-15 Pillar AMBI set is built around a full suite of ambidextrous controls, including bolt and magazine releases. This layout supports standard manual of arms from either shoulder and simplifies operation for left- and right-handed shooters alike. Combined with flared magwells, enlarged trigger guards, and modern rail systems, San Tan Tactical rifles handle well in confined spaces, on the competition line, and in training environments that demand rapid reloads and control under pressure.

Rugged Lifetime Durability

San Tan Tactical uses billet 7075-T6 aluminum, Mil-Spec Type III hard anodizing, and carefully selected components to withstand heavy use. Receivers and complete rifles are designed around tight yet functional tolerances that stand up to field abuse without sacrificing reliability. The company backs its products with a limited lifetime warranty that covers new and used items with proper care, underlining its focus on long-term service life.

Product Focus

Rifles

San Tan Tactical STT-15 and 6mm ARC rifles are engineered from the ground up with reliability as the primary goal. The heart of each build is the Pillar billet receiver set, featuring true matched upper and lower receivers with integral lightening and strengthening cuts that reduce weight without compromising rigidity. STT rifles pair these receivers with quality barrels, tuned gas systems, and curated components like CMC single-stage triggers to support fast follow-up shots and consistent groups. Options in 5.56 NATO and 6mm ARC allow shooters to tailor their setup for patrol-style roles, competition work, or extended-range performance. Attention to gas length, barrel profile, and furniture selection creates rifles that run cleanly and handle well through long days on the range.

Lowers

San Tan Tactical STT-15 lowers were conceived as a true ambidextrous AR-15 foundation. Machined from 7075-T651 billet aluminum, each lower incorporates ambidextrous controls as standard equipment and is shaped for improved ergonomics around the magwell and trigger area. The design accepts common AR-15 lower parts kits and is finished in hard anodizing for abrasion and corrosion resistance. Builders appreciate the clean machining, consistent pin holes, and tight interface with STT uppers, which together reduce wobble and improve overall feel. For shooters who want a serious base for a custom build, STT-15 lowers deliver a balance of strength, fit, and modern control layout.

Parts

San Tan Tactical parts extend the same design philosophy to the rest of the rifle. Pillar billet upper receivers, Lite STT-15L receiver sets for weight-conscious builds, and carefully profiled barrels all support a high standard of performance. Lite receivers retain compatibility with Mil-Spec components while trimming ounces for 3-gun, hunting, or any application where weight matters. Small parts and everything-but-the-lower kits give builders a straightforward path to complete rifles that preserve the ambidextrous control scheme and tight tolerances San Tan Tactical is known for. From receiver combos to individual uppers and lowers, STT parts are intended to work together as a cohesive system rather than a random collection of components.
