Weight. 22oz isn't crazy for a 338 can, but it's quite a bit heavier than the norm across all calibers. It's likely going to have a bigger impact than a TBAC, Omega, or other more common silencer.A tank? In what regard? Length? Weight? Diameter?
It's 10" x 1.8" and weighs 22oz. Thats not outside the norm of 338 cans.
