Compact Barrel with Proven Steel

The 10.5-inch 4150 CMV barrel combines proven metallurgy with black nitride treatment, delivering corrosion resistance and wear protection in a short, maneuverable package. The 1:8 twist rate strikes a balance between lighter and heavier 5.56 NATO projectiles, giving shooters flexibility in ammunition selection. This barrel length is well-suited for builds prioritizing compactness without sacrificing terminal performance at close to moderate ranges.

Carbine-Gas Reliability and Keymod Versatility

The carbine-length gas system pairs with a micro low-profile gas block to ensure consistent cycling across a range of loads. The low-profile design reduces front-end bulk and facilitates a clean handguard fit. The freefloat Keymod handguard, finished with Type III hard coat anodization, offers secure attachment points for accessories while keeping weight manageable. The Keymod interface allows modular placement of lights, foregrips, and other components, and the freefloat design promotes barrel harmonics and mounting versatility.
