The new Fortis Muzzle Brake was inspired by the sharp lines of their brand. Like many of their products, the machining on this brake takes a lot longer than the competition. They take their time to create the very best products out there. Sure, they can make it more simple and in the end, fatten the profit margins -- but they owe it to their 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 their new Fortis Control shield.

I have shot over 1,000 rounds through it already as well as running it in 2 recent USPSA matches. The brake is excellent with 124GR RN at 132PF in my build and gets me super fast split times by keeping things ...Read MoreRead more about This was the perfect brake to cap off

Q: Does this come with shims? I am putting this on a scorpion barrel and I can’t see if it has timing shims or not. If it doesn’t can you please put a link to some on this site? Thanks!
