I bought this and another 3 slot style muzzle break and took them to the range to see which one was going to be riding on the barrel of my Long Range 6.5 Creedmoor. YES, I am running a .338 MB on my much smaller caliber rifle because of the odd ball sized threads I am stuck with. I was VERY impressed with how well it helped alleviate recoil, I was easily able to see impacts which is super nice since I don't usually have a spotter. It only took one shot and I could tell this MB did a much better job of quieting the muzzle blast of my rifle. If you are wondering if this weird looking radial port design is effective, well it is! I did a side by side comparison to another MB that costed $100 more and the OSS B C was every bit as good as the much more expensive one! For the Cost/ Value and how well it performed, I have to give it Five Stars!
