Plan B Scorch Modular Mounting

The Plan B Scorch 3-prong flash hider is designed around a modular mounting system. This means you can swap compatible suppressors and muzzle devices within the Plan B ecosystem without changing the base platform. The 1/2x28 thread pitch is standard for 5.56 NATO barrels, giving you broad compatibility with aftermarket options. The three-prong design helps control flash while keeping profile compact.

Barrel and Gas System Balance

The 16.5-inch Satellite barrel with mid-length gas system creates a balanced platform. The 1:7 twist rate handles a wide range of 5.56 ammunition weights. The micro low-profile gas block keeps the top of the rifle clean and reduces interference with optic mounting. Medium profile barrels offer a good balance between weight and rigidity without the bulk of heavy profiles.

Upper Assembly Components Included

This complete upper includes the bolt carrier group, charging handle, and all upper receiver components. Lower receiver and lower parts kit are not included. You'll need to source those separately to complete the rifle.

Davidson Defense Quality

Davidson Defense components throughout this upper emphasize durability. The 7075 T6 aluminum upper receiver is anodized for corrosion resistance. The bolt carrier group uses 9310 alloy steel with nitride finish for wear resistance. The barrel uses 4150 chrome moly vanadium steel, also nitride finished. These material choices support long-term reliability.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included. BCG and charging handle are included with this complete upper.
