San Tan Tactical Stt 15 5 56 10 5 30RD Odg

About this product

The San Tan Tactical STT-15 is a premium billet AR-pattern pistol chambered in 5.56 NATO, and this Olive Drab Green configuration with a 10.5-inch barrel is priced at $1,129.99. As a firearm, it ships to a licensed FFL dealer for pickup only — it cannot be shipped to a residence.

What is the San Tan Tactical STT-15 good for?

The STT-15 is built for shooters who want a compact, maneuverable 5.56 platform for close-quarters use, home defense, or a range gun that is easier to store and transport than a full rifle. San Tan Tactical positions this as a premium option above mass-market AR pistols, and the 10.5-inch barrel length splits the difference between the maneuverability of a very short pistol and the ballistics of a longer barrel.

What sets the STT-15 apart from a standard AR pistol?

The lower and upper are San Tan's own Pillar billet receiver set, CNC-machined from 7075-T6 aerospace-grade aluminum rather than the forged aluminum most AR-15s use, and the lower is fully ambidextrous with three QD sling attachment points built in. The 10.5-inch barrel is cut from 41V50 vanadium steel with a 1:7 twist rate, threaded 1/2-28 and dimpled for a secure, properly indexed gas block. Inside, it runs a premium CMC flat-face trigger breaking at roughly 3.5 pounds and an enhanced, suppressor-optimized bolt carrier group. San Tan backs its products with a lifetime warranty, and everything is made in the USA.

Is an AR pistol like the STT-15 legal in California?

AR-pattern pistols sit in a genuinely complicated part of California firearms law — features like a stabilizing brace, forward pistol grip, or certain magazine configurations can move a pistol into "assault weapon" territory under state law depending on exact configuration, and federal ATF rules on stabilizing braces have also shifted more than once in recent years. We are not going to tell you this configuration is California-legal without you confirming it — talk to your FFL before ordering about what brace or stock and magazine setup, if any, would be lawful for you to take possession of in your state.

Why choose a billet AR pistol over a forged one?

Most AR-15s and AR pistols on the market use forged receivers, which are strong, proven, and inexpensive to produce at scale. Billet receivers like San Tan's Pillar set start as a solid block of 7075-T6 aluminum that is CNC-machined down to final shape, which allows for design details a forging die cannot easily produce — more material where it counts, cleaner internal geometry, and often a tighter, more consistent fit between upper and lower. It is a more expensive manufacturing process, which is reflected in the price here, but it is also part of why San Tan backs the STT-15 with a lifetime warranty rather than a limited one.

What should I plan to add before shooting the STT-15?

Most buyers pair an AR pistol like this with a red dot rather than relying on the top rail bare, since there are no iron sights included, and a stabilizing brace or a properly configured buffer tube setup for shooting one-handed or with a wrist strap, depending on what is legal in your state at the time of purchase. Budget for those additions on top of the base price if you do not already have compatible gear on hand from another AR build.

Once your order and background check clear through our secure checkout, we will coordinate transfer to the FFL you select.
