About this flash hider
Breek Arms Plan B Sentinel Caged Flash Hider .223/5.56/9mm Luger 1/2x28 Thread Black is a flash hider.
Thread pitch and bore diameter are the two things to confirm: the device has to match your barrel's threads and be bored for your caliber or larger.
California note: a flash hider is a listed feature on a semi-automatic centerfire rifle with a detachable magazine. It works on a fixed-magazine (MagLock or CompMag) build. On a featureless rifle it is replaced with a thread protector or a muzzle brake. See the California Rifle Compliance Guide.
