About a year ago I was considering buying a Wolverine. After reading up on it, I talked myself out of it. Half of the reviews said it's awesome, and the other half say it's loud/causes some guns to beat themselves up without a KNS piston/a waste of time to suppress an AK. Now I find myself looking at them again. I already have other suppressors to cover .30/rimfire/9mm. My hosts for a Wolverine would be SBR'd 104UR and 107CR.

What's the real deal on these?
