The FLASH HIDER by Q is a Quickie Fast-Attach muzzle device built for .338 bore barrels with 3/4 x 24 threads. This version mounts against a standard square shoulder, making it the right choice for barrels that don’t use Q’s tapered shoulder.
Wrench flats are machined directly into the rear for a simple, no-nonsense installation. No special socket. No weird tools. Just grab the correct wrench, torque it down, and get on with your life.
The flash hider design helps reduce visible muzzle flash while providing a secure mounting interface for compatible Q silencers.
