Faxon Firearms Muzzlok 7.62X39mm 3-Port Muzzle Brake 5/8''-24 Threads Blk
$64.39
The Faxon Firearms Muzzlok 7.62x39mm muzzle brake is a field-friendly recoil reducer built for shooters who want simple installation without the usual hassle. Its three-port design captures and redirects propellant gases to the sides, cutting felt recoil across barrel lengths—whether you're running a short 7.62x39 build or experimenting with different setups. Unlike traditional muzzle devices, the Muzzlok's innovative timing system lets you dial in perfect rotational alignment with just an extension nut and a wrench, no crush washer or shims required.
What sets this brake apart is its field-strippable design. You can remove and reinstall it in the field if you need to—say, switching between suppressed and unsuppressed shooting, or swapping uppers without permanent installation headaches. Tighten it to 20–25 foot-pounds and you're done. The salt-bath nitride finish on steel construction is tough and corrosion-resistant, holding up to the grit of actual field use without looking precious or requiring babying.
Faxon's competition team runs this brake on their own rifles, which tells you something: it's been tested in real-world shooting rather than engineered by committee. If you're building or tuning a 7.62x39 upper and want a no-nonsense brake that threads cleanly and doesn't demand special tools or crushers, this is a logical choice.

Frequently Asked Questions
Will this muzzle brake fit my 7.62x39 rifle?
Yes, this brake is compatible with 7.62x39 rifles threaded 5/8"-24. It's also compatible with .308, 6.5, and .300 Blackout platforms sharing the same thread pitch.
Do I need a crush washer to install it?
No. The Muzzlok system eliminates the need for a crush washer. You adjust rotational timing with the extension nut, then torque to 20–25 foot-pounds. This makes installation simpler and faster.
Can I remove and reinstall this brake in the field?
Yes. The Muzzlok design allows you to remove and reinstall the brake without crush washers or shims, making it practical for field switching between suppressed and unsuppressed configurations or when changing barrels.
What finish does it have, and will it rust?
The brake is finished in salt-bath nitride, a durable coating that resists corrosion. It's designed to hold up in field conditions without special maintenance.
