Faxon Firearms MuzzLok SS Plan B Flash Hider 1/2x28 .250" Bore - Stainless

The Faxon Firearms MuzzLok SS Plan B Flash Hider is a stainless steel muzzle device built for rifle shooters who also run a suppressor. Built around Faxon's proprietary MuzzLok quick-detach interface and the Plan B (HUB-compatible) mounting pattern, this flash hider lets you shoot unsuppressed with a reduced flash signature and then drop a compatible Plan B / HUB-pattern suppressor onto the same barrel without timing shims or crush washers. The unit carries a durable black nitride coating for long service life and is threaded 1/2x28 with a .250" bore optimized for .223 Remington / 5.56x45mm NATO cartridges. Made in the USA.

The .250" bore makes this hider the correct fit for typical 5.56 / .223 rifles, where the bore diameter is matched to the projectile for effective flash suppression at rifle pressures. The 1/2x28 thread pitch is the standard for AR-15-pattern barrels, allowing direct installation on any barrel already cut for a common A2-style flash hider. Construction is in stainless steel with a black nitride finish that resists corrosion and wear under hard use, and the hider installs without the crush washers or shims that traditional timing-required muzzle devices demand.

Where the MuzzLok SS Plan B really earns its keep is at the suppressor interface. The Plan B (HUB-compatible) shoulder on the rear of the hider accepts any Plan B muzzle device or HUB-pattern suppressor adapter, giving you a repeatable, shim-free lockup of a suppressor. That lets the same barrel host a bare flash hider for casual or competition shooting and a suppressor for hunting, duty, or range sessions without re-timing the device on the barrel.

A clean, modern flash hider that doubles as a Plan B suppressor mount, the Faxon MuzzLok SS Plan B is a smart upgrade for any AR-pattern rifle running 5.56 NATO where you want one muzzle device to do both jobs.
