San Tan Tactical STT-15 6 ARC Carbon Fiber Barrel 6mm ARC Blue/Black Rifle

Description

Product Overview

The San Tan Tactical STT-15 6 ARC is a precision-focused semi-automatic rifle built around the AR-15 platform. It pairs a matched billet 7075-T6 aluminum receiver set with an 18-inch Proof Research carbon-fiber barrel chambered in 6mm ARC, delivering a lightweight configuration with the reach and performance potential of Hornady’s modern intermediate cartridge. A suppressor-optimized enhanced bolt carrier group, high-pressure-tested and magnetic-particle-inspected bolt, and Crane O-ring upgrade support dependable operation. The rifle is equipped with a CMC 3.5-pound single-stage match trigger, Magpul CTR adjustable stock, Magpul MOE+ grip, MBUS Pro sights, and a 16-inch M-LOK handguard. Its receiver set receives a deep black Type 3 Class 2 hardcoat anodized treatment, while the extended feed ramps and precision-machined matched components contribute to consistent feeding and accuracy. The optic-ready configuration lets users add a preferred red dot, scope, or other compatible aiming system.
