The San Tan Tactical STT-15 (San Tan Tactical part no. STT15-P-556-7) is a 5.56 NATO AR-pattern pistol built on the company’s true, hand-finished, matched pillar-billet upper and lower receiver sets. Its compact 7.5-inch barrel keeps the overall footprint small for a fast-handling, maneuverable pistol, and fully ambidextrous controls — magazine release, safety selector, bolt release, and charging handle — suit right- or left-handed shooters equally well. It feeds from standard AR-15 magazines and holds 30 rounds, and ships without an arm brace, letting the buyer choose their own brace or add one separately. This is a premium, precision-machined AR pistol platform from a builder known for tight tolerances.
