Thread: Muzzle device counts as part of minimum length?

Does a muzzle device that is screwed on with a crush washer count as the total length of your rifle?

I have been told yes by quite a few people, just wondering of anyone has heard different?

I'm building an sbr upper hence the question and plan to use an Ase Utra Borelock can which locks on to the muzzle brake. Cheers.
