I bought a couple of Muzzle Brakes from an old buddy of mine out of Colorado and thought i'd share what I found.

-I bought a steel .308 and aluminum .223
-The only difference I found is the weight of the brake other than that they fire the same.
-I paid 27 bucks for the .223 and 30 bucks for the .308

-At 100 yards my shot group improved by about 1/4" maybe a little more (1/4" MOA)
-The shot velocity improved by 75 feet per second

He builds each one as ordered and custom builds it to your size color etc.
He builds so that the ports face outward and he puts two larger ports on each side of the brake which I found better than a bunch of little holes all over or even three slots on each side. It seemed to release better.
He tapers the end back to the barrel and ships a lock washer with it coated the same as the brake. Installed real easily and quick.

His name is Dave Fulcomer
I was told I can put his website on here so here it is:

I thought these were good brakes especially for as cheap as he is selling them. What does everyone else think?
