Good 223 muzzle break not so good crush washer. - Breek Arms OPMOD 2 Port Muzzle Brake for 223/556 Caliber, 1/2x28 Threads

I like this muzzle break. I bought it to use on a Ruger 22 Charger and not on a 223.

When I test fitted it, it was pretty good but needed about a quarter turn to hit the timing correctly. The crush washer was so stiff, I couldn't get a quarter turn out of it, so I wound up shimming it. With the shims, the timing was close but off by a couple of millimeters past dead on. I could have fixed off by a couple of millimeters ahead of zero, but not past it. .

I'm shooting 3/4 inch, or less, groups at 25 yards after the changes I've made to the Charger and without the muzzle break, so I decided to leave it off because the muzzle break wasn't likely to improve anything up to the point of a just noticeable difference, and there was a chance it would degrade the accuracy.

However, this is a well made break, but it needs some shims, as well as a crush washer, in the package.
