Description
Muzzle rise is the enemy of a fast second shot, and on a lighter .308 or 7.62 rifle it can throw your sight picture off in a hurry. The Fortis RED, short for Rapid Engagement Device, is built to keep the front end flat and settle the gun back on target so you can stay in the fight or stay competitive. Two side baffles paired with a couple of exhaust ports along the top vent gas where it does the most good, pushing back against recoil and that upward kick you get with a full-power .30 caliber round.
What Makes the Fortis RED 7.62 Tick
This brake is machined from 4140 steel and finished in a black nitride coating, which adds surface hardness and helps it shrug off rust and the corrosive junk that builds up at the muzzle. It measures 2.75 inches long, weighs in around 3.8 ounces, and runs 5/8×24 threads to fit standard .308 and 7.62×51 AR-10 barrels. The edges are smoothed over so it won't snag on gear, and the open port design makes cleaning quick when carbon starts to cake up.
How the Fortis RED Brake Earned Its Name
Fortis didn't just design this one in a vacuum. It was put in the hands of military and law enforcement folks, then handed off to the 3-gun crowd who run their guns hard and fast. It also held up under full auto testing, which tells you the design has been through the wringer. The RED is control shield compatible too, so if you run a blast shield or similar accessory, it plays nice.
If you're building or upgrading an AR-10 and want a proven brake that looks as clean as it shoots, the Fortis RED is a straightforward, made-in-America choice that gets the job done without a lot of fuss.

Frequently Asked Questions
What thread pitch does the Fortis RED 7.62 use?
The Fortis RED 7.62 comes threaded 5/8×24, which is the standard for .308 and 7.62×51 AR-10 barrels. It installs on most .30 caliber rifles with matching threads. A crush washer is included in the box to get you timed and torqued correctly.
Does the Fortis RED brake come with everything needed to install it?
Yes, the brake ships with a crush washer, so you have what you need to mount and time it on a standard 5/8×24 muzzle. You'll want a wrench and vise block to get it torqued down properly. That's typical for any muzzle device install.
Will the Fortis RED reduce recoil on my AR-10?
It's built specifically to fight muzzle rise and felt recoil on 7.62 and .308 platforms. The side baffles and top exhaust ports redirect gas to keep the front end flat, which helps you settle back on target faster between shots. That's a real advantage on lighter AR-10 builds where muzzle climb tends to be more noticeable.
Is the Fortis RED muzzle brake control shield compatible?
Yes, the RED is designed to work with control shields and similar blast-mitigating accessories. That makes it a flexible pick if you plan to run a shield down the road. The nitride finish and smoothed edges also keep it snag-free and easy to clean.
