Comstock Armory Hybrid 9mm Flash Hider/Muzzle Brake – 1/2×28
The Comstock Armory Hybrid Muzzle Device (SKU: HYB-12-9-PW) is a versatile suppressor-ready mount that blends the attributes of a flash hider and a muzzle brake. It is designed to offer a balanced shooting experience by reducing both recoil and visual signature without the extreme blast common to traditional brakes. The HYB-12-9-PW is part of the Plan-B compatible family, specifically engineered to interface with .900″-24 adapters such as the Comstock LPA, Q Plan-B, and Rearden Atlas.
- Dual-Function Design: Provides measurable recoil reduction while effectively breaking up muzzle flash, making it ideal for low-light tactical use or competitive shooting.
- Sacrificial Baffle Protection: When used with a suppressor, the device’s internal geometry redirects expanding gases to take the brunt of the erosion, extending the life of the suppressor’s expensive blast baffle.
- No Timing Required: The rotationally symmetric porting eliminates the need for shims or crush washers, ensuring a simple, concentric “direct-to-shoulder” installation.
- Pin & Weld Ready: Includes a pre-drilled hole for permanent attachment to 14.5″ barrels to reach the legal 16″ non-NFA overall length.
