The Warrior Systems Sentinel is a precision-machined 5.56mm modern sporting rifle engineered for durability, control, and field-ready performance. Built in-house with CNC-machined billet upper and lower receivers, the Sentinel is designed to deliver a tight, match-grade fit and consistent reliability under demanding conditions.

At its core, the rifle features a 16-inch 4150 chrome moly barrel with a black nitride finish and a 1:8 twist rate, offering a balance of durability and versatility across a wide range of ammunition types. A mid-length gas system supports smooth cycling and reduced recoil impulse.
The Sentinel is equipped with a WSM 15-inch M-LOK free float handguard, providing a rigid yet lightweight platform for accessory mounting. Shooter-focused enhancements include a flared magazine well for faster reloads, a threaded bolt catch roll pin for simplified maintenance, and an integrated enlarged winter-style trigger guard for improved usability in adverse conditions.
Ergonomics are upgraded with a B5 Bravo six-position collapsible stock and B5 P23 pistol grip, giving users improved comfort, stability, and weapon control. The rifle is also outfitted with a WSM mock suppressor and includes a color-matched 50-round drum magazine for extended capacity.
The Sentinel is available in four durable color finish options, designed to enhance corrosion resistance and long-term wear protection. Each rifle ships with a discreet carry case and is backed by a limited lifetime warranty.
