Frequently Asked Questions

Will this muzzle brake fit my AR-15 barrel?

Yes — as long as your AR-15 barrel has a standard 1/2x28 threaded muzzle, this brake will install directly. This is the most common thread pitch for AR-15 barrels chambered in 5.56 NATO and .223 Remington. Always verify your barrel's thread pitch before ordering. A crush washer is included to ensure a proper and secure installation.

How does this muzzle brake compare to a flash hider or compensator?

A muzzle brake is specifically designed to redirect propellant gases to counteract recoil and muzzle rise, which is its primary function. Unlike a flash hider — which focuses on reducing visible muzzle flash — or a basic compensator, the Fortis Muzzle Brake prioritizes felt recoil reduction and muzzle stability. This makes it especially well-suited for high-volume shooting and competitive applications where rapid target reacquisition is critical.

Is the nitride finish durable enough for hard use?

Absolutely. Nitride (also marketed as Melonite or QPQ) is a case-hardening surface treatment that penetrates the steel rather than simply coating it. The result is exceptional corrosion resistance, improved surface hardness, and a finish that won't chip or flake under sustained fire or harsh environmental conditions. It's the same finish used on premium barrels and BCGs for good reason.
