Plan B Muzzle Device Ecosystem

The. Breek. Arms. Plan B Scorch flash hider is built for modular suppressor mounting. This 3-prong design supports quick-detach suppressor systems within the. Plan B ecosystem, letting you add sound reduction without replacing the muzzle device. The hardened 4140 steel construction ensures durability through repeated mounting cycles.

Barrel and Gas System Performance

The 16-inch carbine-length gas system keeps overall rifle length manageable while delivering reliable cycling with standard 5.56 NATO ammunition. The nitride finish on the 4150 chrome moly barrel provides corrosion resistance and extended service life. Medium profile construction balances weight and rigidity without excess barrel mass.

Handguard and Mounting Flexibility

The free-float 15-inch quad rail handguard isolates the barrel from contact with the upper receiver, reducing harmonics and improving shot-to-shot consistency. Quad rail configuration provides four mounting surfaces for lights, lasers, grips, and other tactical accessories.

Lower receiver not included. BCG and charging handle are included with this kit. Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. May. Dropship from. Davidson. Defense.
