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.

Looks absolutely gorgeous on my CETME-C. If you told me this was the brake they came with, I would believe you. It fits very well, though I have absolutely no idea whether it does anything whatsoever to mitigate recoil or muzzle flash; This serves a wholly cosmetic purpose to me. Side note, the internal threads one can see from the end, facing inward.. they're purely cosmetic. Not the same as the inboard thread, it's actually a totally different pitch (3/8-16 if I had to guess) and it's there *only* to look cool. I just found that interesting.
I use these on alot of my builds and for guns under 18" the blast sheild that just threads over is a must.
This Flash Hider is clean and adds that cherry on top to my AR barrel. I also have the Breek Arms CASTLE BLAST SHIELD Concussion Device that is easily added and removed and I just love the all around feel and look. Helps the recoil on my AR and makes it look very professional as well. Love it!
Been waiting a good while for the can to come back in stock, finally got both and I’m super pleased with the results. Keep up the great work Breek Arms!!!
Great flash hider for a fraction of the price. Performs flawlessly.
This is my second one. Have one on a 11.5 and the new one on my 16”. One of the best flash hiders I’ve ever used very much mitigates all flash coming out of the gun. Also the finish on these is great and tough. As well as looking good they work the best.
