San Tan Tactical STT-15 5.56 NATO 16″ 30-Round AR Rifle

Description

The San Tan Tactical STT-15 5.56 NATO 16″ 30-Round AR Rifle is a hand-built, match-grade platform for shooters who demand precision and reliability from the ground up. It starts with a matched, hand-finished pillar billet receiver set—no loose tolerances, no slop. The fit is so consistent that every component seats exactly where it should, shot after shot. Chambered in .223 Rem/5.56 NATO with a 16-inch barrel and 30-round capacity, this rifle is built for range work, competition, and general sporting use. The fully ambidextrous lower and three QD sling attachment points make it equally at home in a left- or right-handed shooter’s hands.

Key Features

• Matched Billet Receiver Set: Why it matters: Hand-finished pillars ensure the upper and lower lock up tight with zero wobble, improving accuracy and consistency over forged receivers.
• Fully Ambidextrous Lower: Why it matters: Ambidextrous bolt catch, magazine release, and safety selector let left-handed shooters run the rifle as fast as right-handed shooters, without awkward hand swaps.
• Three QD Attachment Points: Why it matters: Two on the handguard and one on the lower give you multiple sling mounting options for quick transitions or stable shooting positions.
• Camouflage Cerakote Finish: Why it matters: This durable, corrosion-resistant coating reduces glare and blends with outdoor environments—ideal for hunting, competition, or range days.
• 16-Inch Chrome-Lined Barrel: Why it matters: The 1:8 twist rate stabilizes a wide range of bullet weights (55–77 grains), and the chrome lining extends barrel life while simplifying cleaning.

Who It’s For

This rifle suits the shooter who wants a premium, semi-custom AR without the wait time of a full custom build. It’s for the competitor who needs a reliable, accurate gun for three-gun or tactical matches. It’s for the hunter who wants a lightweight, compact 5.56 for varmints or small game. And it’s for the traditionalist who appreciates billet craftsmanship and a hand-finished fit—not a mass-produced lower that rattles.

Pros & Cons

Pros: Rock-solid receiver fit, ambidextrous controls out of the box, durable Cerakote finish, accurate 1:8 twist barrel, three QD points for sling versatility.

Cons: The camouflage Cerakote may not appeal to shooters who prefer a solid color or black finish. The billet set is slightly heavier than a forged receiver—about 0.3 lbs more, per San Tan specs. No iron sights included, so budget for optics or backup sights.
