Title: Installing a muzzle brake on a Kimber Montana
Post by: CaNINE on July 27, 2020, 03:23:39 PM: I ordered a factory brake from Kimber for my 280AI. The brake is pitched 7/16x28. Leave it to Kimber to pick an odd thread pitch. Trying to determine the right tenon to use. Any of you guys install one of these brakes?

Yes this is what I was looking for. We contacted a couple different barrel manufacturers and confirmed .435. It’s a toothpick of a barrel.
