Comstock Armory Full Size 9mm Flash Hider – 1/2×28
The Comstock Armory Full Size Flash Hider (SKU: FHL-12-9-PW) is a suppressor-ready muzzle device designed for 9mm platforms. It serves as both a high-efficiency flash hider and a mounting interface for Plan-B style suppressor adapters. The FHL-12-9-PW is engineered to deliver superior flash mitigation while protecting your suppressor’s longevity. It is specifically designed to be compatible with the .900″-24 adapter system used by the Comstock LPA, Q Plan-B, and Rearden Atlas.Â
- Blast Baffle Protection: Unlike traditional flash hiders, the FHL redirects expanding gases outward, significantly reducing wear on a suppressor’s blast baffle.
- No Timing Required: The rotationally symmetric design allows a simple “direct-to-shoulder” installation without shims or crush washers.
- Pin & Weld Ready: The device comes pre-drilled to facilitate permanent installation on 14.5″ barrels, helping them reach the legal 16″ non-NFA overall length.
- Standard Tooling: Features 3/4″ wrench flats for easy installation and precise torque application
