Overview
The San Tan Tactical Patrol Series SBR is a short-barreled rifle chambered in 5.56 NATO, offering the duty-grade Patrol Series build with a buttstock under NFA registration. It is available with 10.5-inch, 11.5-inch, or 12.5-inch 4150 chrome-moly-vanadium barrels on a carbine-length gas system tuned for suppressed and unsuppressed fire. Built on San Tan Tactical's fully ambidextrous billet receiver set with the in-house STT Wedge Lock M-LOK handguard, it combines a CMC Triggers Combat Curved 3.5-pound trigger, an STT Duty bolt carrier group with ArmorLube DLC coating and dual ejectors, a BCM MK2 receiver extension, a B5 SOPMOD Bravo stock, and a B5 P23 grip, shipping with a Magpul PMAG and an A2 birdcage muzzle device. As a registered SBR it provides a true buttstock for improved control over the equivalent braced pistol, in a compact, fully ambidextrous duty package.
