Faxon MuzzLok Mini Plan B 3-Prong Flash Hider 5/8x24 .338 - Muzzle Device

Full flash suppression on a timed, repeatable mount — without crush washers or shims. The Faxon MuzzLok Mini Plan B 3-prongFlash Hider threads onto 5/8x24-threaded .308-class and larger caliber barrels and locks precisely with a left-hand MuzzLok timing nut, giving you repeatable port orientation every time the device comes off for cleaning or suppressor installation.

The Faxon MuzzLok Mini Plan B 3-prong Flash Hider is a .338-inch-bore shorter, more compact muzzle device machined from 17-4 PH stainless steel with a nitride finish, designed for 5/8x24-threaded barrels and configured for direct integration with the Plan B suppressor ecosystem.

Four features define the MuzzLok system's advantage over conventional timed muzzle devices. The left-hand MuzzLok timing nut replaces crush washers and timing shims entirely — thread the device to the desired orientation, tighten the nut, and the position locks repeatably without any consumable hardware. The Plan B interface thread (29/32-24 UNEF-2A) mates with a Plan B to HUB adapter for direct compatibility with 1.375-24 HUB-mount suppressors including the Faxon HARMONIX and CORESYNC when configured appropriately. Heat treated 17-4 PH stainless steel provides exceptional hardness and corrosion resistance at the muzzle — where heat, carbon, and moisture combine to accelerate wear on lesser materials. The 3-prong design significantly reduces visible muzzle flash at typical engagement distances, making it particularly effective for suppressor-host builds where the device is removed and reinstalled regularly.

Compatible with .338" bore diameter and smaller. Requires a Plan B to HUB adapter for use with 1.375-24 HUB-mount suppressors. Minimum 20 ft-lbs final lockup torque recommended.
