Key Features
- Pillar Billet Receiver Set – Made from 7075 T6 aluminum, the receiver is heat-treated and precision-machined for a tight fit that resists wear over thousands of rounds.
- Full Ambidextrous Controls – Safety selector, bolt catch, and magazine release are mirrored on both sides, so left-handed shooters can run the gun without changing their grip.
- 10.5-Inch Barrel – Short enough to maneuver easily in tight spaces (home, vehicle, or range bay) while still delivering reliable 5.56 ballistics at typical engagement distances.
- 30-Round Magazine – Comes with a standard-capacity 30-round mag, giving you sustained firepower without needing to reload as often during training or defense.
- OD Green Finish – The durable anodized coating resists corrosion and scratches, plus it blends well with outdoor gear or tactical kit.
Who It’s For
The STT-15 is built for shooters who want a compact, reliable pistol-caliber carbine (AR pistol) that works for home defense, range practice, and training. It’s a great fit for families teaching new shooters because the ambidextrous controls make it easy for both righties and lefties to learn safely. Beginners will appreciate the predictable recoil of the 5.56 round and the simple manual of arms.
Pros & Cons
- Pro: Ambidextrous controls out of the box – no need to buy aftermarket parts for left-handed use.
- Pro: Compact size makes it easy to store in a safe or carry in a range bag.
- Con: The 10.5-inch barrel produces a louder report and more flash than a 16-inch rifle; you’ll want hearing protection and a muzzle device if shooting indoors.
- Pro: 7075 T6 aluminum receiver is stronger and more durable than 6061, so it holds up to heavy use.

FAQ
Is the San Tan Tactical STT-15 legal to own as a pistol in my state?
This firearm is classified as a pistol under federal law because it has a barrel under 16 inches and is designed to be fired with one hand. However, state and local laws vary. Check your state’s regulations on AR pistols, especially regarding barrel length, overall length, and magazine capacity (30-round mags may be restricted in some states). We recommend consulting a local firearms attorney or your state’s attorney general’s office.
Can I attach a brace or a suppressor to this STT-15?
Yes. The STT-15 has a standard buffer tube that accepts most pistol braces (e.g., SB Tactical, SBA3). The barrel is threaded 1/2×28, so you can add a suppressor or muzzle brake. If you add a suppressor, you must comply with NFA rules (tax stamp, ATF Form 4). Always verify local laws before modifying.
Does the STT-15 come with a case or extra magazines?
It ships with one 30-round magazine. A hard case is not included, but we recommend picking up a padded soft case or a lockable hard case for safe transport. We sell several options in our accessories section.
How does the STT-15 shoot compared to a 16-inch rifle?
The 10.5-inch barrel will have slightly more muzzle blast and flash, and velocity drops about 100-150 fps compared to a 16-inch barrel. For home defense distances (0-50 yards), the difference is minimal. Recoil is still mild, making it a great training gun for new shooters.
