Precision in a compact package is the priority for operators and serious shooters who demand repeatable accuracy, robust materials, and thoughtful ergonomics. A modern AR-15 pistol that blends aerospace-grade metallurgy with meticulous machining can deliver that performance without excess weight or unnecessary features.

SAN-TAN TACTICAL STT-15

What makes the STT-15 standout

The SAN-TAN TACTICAL STT-15 is engineered for precision and performance. Its true matched, hand-finished pillar billet receiver set is more than marketing — hand-fitting and matched serial numbers reduce play between upper and lower, yielding a tighter lockup and more consistent group sizes. The upper is a single piece of 7075T6 Certified Aerospace Aluminum, chosen for its strength-to-weight ratio and proven longevity under hard use.

Barrel, chamber, and accuracy-focused machining

The STT-15’s San Tan 5.56x45mm barrel is made from 41V50 vanadium steel with a 1:7 twist rate — ideal for stabilizing heavier bullets commonly used for longer-range precision or barrier-penetrating needs. Critical surfaces — bore, receiver extension face, barrel nut threads and barrel extension — are machined in a single operation to maintain perfect concentricity and perpendicularity to the barrel assembly. That single-setup machining is a significant accuracy advantage compared with parts fitted after separate operations.

Control, ergonomics, and modularity

The fully ambidextrous STT-15 lower provides operational flexibility for left- or right-handed shooters and includes three QD attachment points for slings or quick-detach mounts. Barrel is threaded 1/2-28 and features dimpled gas block alignment, which secures the gas block for consistent gas system timing — important for reliable cycling and consistent recoil impulse.

For tactical applications or precision-focused carry setups, the STT-15’s matched receiver set and hand-ground fit deliver repeatable performance shot after shot.

Who should consider the STT-15

Operators, competition shooters, and precision-minded enthusiasts who want a compact 5.56x45mm platform will find the SAN-TAN TACTICAL STT-15 compelling. Its aerospace-grade upper, hand-finished matched receivers, and competition-caliber barrel specs make it suitable for duty, range, or dedicated short-barrel precision roles.
