San Tan Tactical Patrol Series Rifle
San Tan Tactical · Carbine · In Production · 2024
Also known as: Patrol Series Rifle 16", STT Patrol Rifle
Overview
The San Tan Tactical Patrol Series Rifle is a duty-oriented 16-inch AR-15 semi-automatic carbine chambered in 5.56 NATO, developed after roughly two years of destructive and longevity testing to prioritize robust reliability with high-quality components. It is built on San Tan Tactical's fully ambidextrous billet receiver set and uses a 16-inch 4150 chrome-moly-vanadium barrel with a carbine-length gas system, an A2 birdcage flash hider, and the company's in-house STT Wedge Lock M-LOK handguard. The build pairs a CMC Triggers Combat Curved 3.5-pound trigger, an STT Duty bolt carrier group with ArmorLube DLC coating and a dual-ejector design, a BCM MK2 receiver extension, a B5 SOPMOD Bravo stock, and a B5 P23 pistol grip, and ships with a Magpul PMAG. Unlike the polished pillar-billet STT-15 line, the Patrol Series is configured as a hard-use duty rifle optimized for both suppressed and unsuppressed shooting, while retaining San Tan Tactical's signature 100% ambidextrous controls.
