Big Bore Black Seventeen Seventy Six 5/8x32

This brake works amazingly for 450 bushmaster ARs. I have used it for my personal gun and several others I’ve built for clients. It is a bit loud, but it will substantially reduce recoil. I have tried many different 450 BM brakes, from tankers to flash hiders… you will not find a better brake for the money than this one. I’ve only found one that worked marginally better, but it was upwards of $180. If you’re on the fence, just buy it. You will be grateful you did later.

Excellent product, excellent value. This is my second brake of this type, I removed my factory brake and tested with only a thread protector. Installing this brake really tamed down my .450 bushmaster. Should the need arise I will not hesitate to buy another one. Big bonus - finding a brake with 5/8x32 thread pitch is difficult but finding one that works this well is awesome!

This is the second one I purchased The fit and finish is great. They work perfect on my rifles. Will buy more in the future.
