Our new
Fortis
Muzzle
Brake
was inspired by the
sharp
lines
of our brand. Like many of our products, the machining on this
brake
takes a lot longer than the competition. We take our time to create the very best products out there. Sure, we can make it more simple and in the end, fatten the profit margins -- but we owe it to our customers to create not only a product, but an amazing experience. Try the new
muzzle
brake
once and you'll be glad you did. The performance is unmatched and
muzzle
rise is non-existent. Keep your speed and accuracy up. Put more down range and on target.
Be sure to verify your thread pitch.
**Compatible with our
old Gen 1 Fortis
Control shield.

Very nice machining and cool design.
Very nice machining and cool design. This muzzle will be a great addition to my 300blk build. Will get the Control for added cool factor and, of course, function, but later next month.

Pretty wild looking little brake
Pretty wild looking little brake, I really like the compatibility with the control shield so I can avoid being "that guy" if I swing by an indoor range this winter. Easy to install and shipped quickly.

300 BLK Muzzle Brake
I use all products for my builds. This is my first muzzle brake bought and will purchase again for future builds. Besides quality, durability and coolness factor this was a great addition to my 300 BLK AR-15. I'm excited for new products coming soon and being produced. Thanks Fortis

Questions and Answers
Q:
Kinda confused on what control to get with this
Asked by:
Nicolas Fields
- 4/30/2025
A:
The original Control Shield is no longer available for this model. We recommend upgrading to the new Slipstream Muzzle Brake and Control Shield Gen II.
Both items can be purchased separately. Links below:

Q:
Hey guys would this fit a 9mm Ar style rifle?
Asked by:
The johnson’s
- 2/13/2025
A:
This depends on the thread pitch of your barrel. For a 9mm AR, the common thread size is typically 1/2x28. However, the thread pitch of this muzzle brake is 5/8x24, so it generally will not fit.
Additionally, a brake designed for .30 caliber rifles might not be as effective for a 9mm AR, which has less recoil and a smaller diameter bullet. Ideally, you would want a brake specifically designed for 9mm, as it would be better optimized for the cartridge's characteristics. We recommend using our 9mm muzzle brake, linked below.

Q:
Will this work on a 308 rifle or will it damage the rifle
Asked by:
William Parten
- 3/25/2023
A:
It will work with a 308 rifle but is not specifically tuned for .308. With the port design it will push your muzzle down quite a bit.
