Precision-Engineered Barrel and Gas System

Freefloat M-Lok Handguard with Integrated Features

The 15-inch M-Lok handguard provides a full-length freefloat design that eliminates barrel contact for improved accuracy potential. Trapezoid cuts reduce weight without sacrificing rigidity, while the integrated handstop enhances control and hand positioning. Anti-rotation tabs ensure rock-solid lockup with the upper receiver, and the partial Picatinny rail allows for front sight or accessory mounting without adding unnecessary weight.

Durable Upper Receiver and Bolt Carrier Group

Machined from 7075-T6 aluminum and finished with a hard anodized coating, the upper receiver features M4 feed ramps for reliable feeding with a variety of ammunition types. The 9310 alloy steel bolt carrier group is treated with a nitride finish, offering excellent wear resistance, reduced friction, and easier cleanup after extended shooting sessions. The included mil-spec charging handle completes the upper assembly with proven reliability.

Adjustable Stock and Buffer System

The adjustable carbine stock constructed from nylon-reinforced polymer offers six positions for length-of-pull adjustment, ensuring a comfortable fit for shooters of all sizes. The mil-spec heavy-duty 6-position buffer tube and standard carbine buffer (3 oz) provide the foundation for smooth, reliable operation. The 1/2x28 GI birdcage flash hider reduces muzzle flash and protects threads when not using a suppressor or muzzle brake.
