Plan B Scorch Modular Mounting Ecosystem

The Plan B Scorch 3-prong flash hider is built for the Plan B muzzle device ecosystem, supporting modular suppressor mounting and accessory compatibility. The Scorch's precision-machined design reduces flash signature while maintaining the compact profile needed for mid-length gas systems. This modular approach lets you upgrade or swap components without replacing the entire muzzle device assembly.

Ronin Competition Satellite Barrel Performance

The Satellite barrel combines 4150 Chrome Moly Vanadium steel with QPQ nitride finishing for a balance of durability and accuracy. The medium profile keeps weight manageable while the 1:7 twist rate stabilizes heavier ammunition, making this barrel suitable for both standard 55-grain rounds and tactical loads up to 77 grains. Nitride finishing provides corrosion resistance and extended service life without the added cost of stainless steel.

Freefloat Design and M-Lok Compatibility

The freefloat handguard eliminates contact between the barrel and furniture, supporting shot-to-shot consistency critical for precision work. The M-Lok mounting system provides lightweight modularity without the rail mass of traditional Picatinny designs, letting you add only the accessories you actually need while keeping the platform streamlined.

Black Diamond Series Billet Upper Receiver

The billet upper receiver is machined from 6061-T6 aluminum and finished with Type III hard coat anodize, offering a clean aesthetic and enhanced durability. The slick side design pairs cleanly with free-floating handguards and minimizes visual clutter for shooters who prefer minimalist setups.
