The SFMB-556-1/2-28 works very well to eliminate muzzle rise. When my brother was shooting my AR with this muzzle device on, I saw zero muzzle rise! I also like the fact that you have options with this muzzle device on your AR to attach suppressors and the Warden blast device.
I received this muzzle brake showing obvious usage (residue build up inside the corners of the brake and wrench marks), also missing in this package were the wrench and shim/spacers it was supposed to come with. I was excited to have this product in prepping to take a CQB course. I'll be returning...

The price is a bit steep but you certainly do get what you pay for. Comes with shims and easy instructions for proper timing for you DIY'ers. Make sure you clean those threads before using rocksett.
The brake does its job and it does it very well. I have to say this is very comparable to the lesser expensive jcomp / king comp with the usability with your warden or for you lucky fellas, suppressors.
I have tested this for the 5.56 and will be getting another one for my 300 as well.

Did some research online and saw that this Surefire suppressor host was the quietest of the bunch. I would have to agree. Super happy with this piece. If I ever decide to get another firearm that can host my SPS300... I will 100% be buying another one of these for the muzzle break.
