I was wondering if there have been any tests regarding bolt on muzzle brakes? Specifically how they may affect accuracy.

I have seen a few youtube clips where the recoil reduction of the clamp on muzzle brake is addressed, and it appears that they work well in that regard. Although some videos mention that accuracy did not degrade, I would like to know if any of you have tried a bolt on muzzle brake, such as Kahntrol, and if so - how did it affect the accuracy of your rifle?

Thanks.
