Key Features
- True Matched Billet Set: Upper and lower are hand-finished as a pair for tight lockup and zero wobble. Why it matters: consistent accuracy shot after shot, even on dusty ranch roads.
- Fully Ambidextrous Lower: Ambidextrous bolt catch, magazine release, and safety selector. Why it matters: left-handed or injured shooters can run this rifle without fumbling.
- Three QD Attachment Points: Two on the handguard, one on the lower receiver. Why it matters: sling swaps fast for hands-free work on the property.
- MultiCam Black Cerakote Finish: Durable coating that resists scratches, rust, and UV fading. Why it matters: one less thing to worry about when the rifle is leaning against a fence post all day.
- 16″ Barrel with Mid-Length Gas System: Smooth cycling and reliable feeding with most factory .223/5.56 loads. Why it matters: less recoil impulse means faster follow-up shots on varmints or steel.
Who It’s For
This rifle is for ranchers, rural workers, and utility shooters who need a dependable tool, not a safe queen. If you patrol fence lines, control predators, or run range drills after chores, the STT-15 fits. It’s also a solid choice for the left-handed shooter who wants ambi controls out of the box.
Pros & Cons
- Pros: Tight billet fit, ambi controls, durable Cerakote, three QD points, reliable mid-length gas system.
- Cons: MultiCam Black finish adds cost over basic black; some users report the ambi bolt catch takes a few rounds to break in.

FAQ
Does this rifle come with a magazine?
Yes, it ships with one 30-round magazine. The finish on the mag may vary, but it functions with standard AR-15 mags.
Is the MultiCam Black finish durable enough for daily carry?
Yes. Cerakote is a ceramic-based coating that resists scratches, corrosion, and heat. It holds up better than standard anodizing in rough conditions.
Can I use this rifle for left-handed shooting?
Absolutely. The lower receiver is fully ambidextrous, including bolt catch, magazine release, and safety selector. Lefties can run it without swapping parts.
What gas system does the 16″ barrel use?
It uses a mid-length gas system, which provides smoother cycling and less felt recoil compared to a carbine-length system.
