Kimber Ascent would already be threaded, 7/16"x???. Would need a bushing to bump it to 5/8"x24 tpi. Christensen Arms web says Ridgeline barrels over 25 caliber are threaded 5/8"x24. No adapter needed. Should have sufficient shoulder to properly seat/support the suppressor. Not crazy about CF barrels. However, this is the reason I would prefer a Ridgeline over a Mesa in the CA line up.
