Note: For the BLEM Castle Blast Shield option, the blemishes are small scratches on the inside of  the blast shield. They are from removing supports during the annodizing process, they are not a used item.

Breek Arms offers a low cost option to competitive muzzle brake designs used for increasing muzzle control as well as adding a custom design to your platform. The combination of ports and holes helps disperse gases up, left and right to reduce the level of muzzle climb and reduce the visible flash when firing. Also, the included outside thread allows you to quickly detach your own blast shield or suppressor.

    Everything I have purchased from Breek has been top notch. Threads are clean machining marks are subtle at worst. For the price point I truly do not think you can beat any of these products.

    Great flash hider for my SBR. Combine it with the Castle Blast Shield if you're in closer proximity to others and you're good to go. Great bargain and love the look of the blast shield.

    3 Prong Flash Hider

    I got it in the mail yesterday which was fast considering the holidays. I put in on my AR and so far it looks great and fits just right by sitting out in front of my M-lok rail! It’s exactly how I wanted it to look, but I still have to go shoot with it on(I’ll update afterward). Now I’m just waiting for the Castle Blast Shield to arrive which I’m sure will look perfect as well!

    I love this comp. the streamline design is very cool. And the tuning fork ring adds to the appeal. Added an FDD from another comp, works out very well. Looks very nice on my Odin Works 300 B.O. for my pistol setup. the slotted ports ensure a very smooth shot recovery and transition. Its aesthetically pleasing and doesn't require any gunsmithing only needed to use the crush washer, although the comp comes with both the locknut and crush washer. I highly recommend this comp.
