Plan B Scorch Modular Mounting

The included Plan B Scorch 3-prong flash hider is built for quick-swap suppressor compatibility. This muzzle device supports the Plan B and Atlas mounting ecosystem, allowing you to attach and remove suppressors without tools. The modular design means you can configure your setup based on your needs, whether that's flash reduction, suppression, or a bare muzzle.

.223 Wylde Chamber and Barrel Specifications

The .223 Wylde chamber accepts both .223 Remington and 5.56 NATO ammunition, giving you flexibility in what you shoot. The 1:7 twist rate stabilizes a wide range of bullet weights from 40 grains up to 77 grains, making this barrel suitable for precision shooting, hunting, or general range work. The 16.5-inch length with mid-gas system provides a balance between velocity and handling, with a government profile that's proven across thousands of builds.

Freefloat Handguard and Ergonomics

The 15-inch M-Lok handguard is aircraft-grade aluminum with a Type III hard coat anodize finish, which resists wear and corrosion. The freefloat design means the barrel sits independently of the handguard, eliminating contact points that can affect accuracy. M-Lok slots run along the handguard for mounting optics, lights, or accessories without adding unnecessary weight.
