Breek Arms’ lineup of Outside Threaded Muzzle Devices is an affordable upgrade that gives you the option to run a flash hider or muzzle brake while utilizing our Breek Arms Castle Blast Shield as a forward blast diverter or concussion device. Simply slide the blast shield over the outside of the muzzle device and turn the blast shield on. This gives the shooter a more pleasant experience when firing especially for shorter platforms that tend to have an overbearing concussion. Our new Caged Flash Hiders have added bridges between the 3 prongs to increase durability and give it a more classic muzzle device look.

Flash hider and blast can
Great machining. Love the look on 300 blackout. Will be better than the A2 style flash hider and lees conclusion at the ears.
Love the combo set. Real sleek and the finish is nice. Will be purchasing one for my ARP.
Great price, great product
I was looking around for a flash can-ish device. I like the fact that the can is removable to use the flash suppressor. The products came quickly, were of great quality, and the customer service is amazing. Will be buying more.
