Dominate the tactical space with the all-new TYPE-A SR Series 11.5" 5.56 NATO Rifle. Engineered from the ground up for uncompromising durability, reliability, and consistency, this ultra-compact powerhouse is built to exceed the demands of professional and defensive shooters alike. At the heart of this rifle lies a premium 11.5-inch 4150V chrome-lined barrel with precision 5R rifling, perfectly tuned via the revolutionary RS Gas Manifold System—the industry's only fully serviceable adjustable gas block that can be maintained without removal. Housed in precision-machined 7075-T6 aluminum receivers and finished in a striking clear hardcoat anodization, this rifle delivers rugged beauty and extreme wear resistance. Paired with a meticulously REM-polished CrN bolt carrier group, a crisp match-grade 2-stage trigger, and a bomb-proof MK-10.8 Quad Rail, the 11.5" SR Series offers unparalleled handling and relentless performance in any environment.

Revolutionary RS Gas Manifold System
Features a fully open/closed adjustable gas block and straight threaded gas tube, allowing you to custom-tune and service the gas system without removing it from the rifle.

Premium 5R Chrome-Lined Barrel
The compact 11.5-inch 4150V steel barrel utilizes advanced 5R rifling and a MagPhos finish to maximize accuracy, reduce fouling, and ensure exceptionally long barrel life.

Ultra-Rigid MK-10.8 Quad Rail
Constructed from 6061-T6 aluminum with an extended barrel nut and anti-rotation tongue-and-groove system, delivering massive accessory real estate and guaranteed zero retention for your aiming devices.

Frictionless REM-Polished BCG
The M16-style billet 8620 carrier and MPI-tested 9310 steel bolt feature a proprietary REM polish and Certess Nitro CrN coating to dramatically reduce friction, wear, and cleaning time.

Match-Grade 2-Stage Trigger
Machined in-house from vacuum heat-treated S7 Tool Steel, providing a crisp, predictable 3.5–4.0 lb pull (2.5 lb first stage, 2.0 lb second stage) for surgical shot placement.

Fully Ambidextrous Controls
Equipped with a TYPE-C ambi charging handle, a 90°/70° short-throw safety selector, and extended billet catches to ensure high-speed, intuitive operation from either shoulder.

Precision Clear Anodized Receivers
Machined from 7075-T6 aluminum with a stunning Type-III clear hardcoat anodization, offering extreme structural integrity, enhanced M4 feed ramps, and an internal wire-EDM magwell flare for lightning-fast reloads.
