Thread Barrel for Customer's Muzzle Brake or Suppressor

Thread Barrel for Customer's Muzzle Brake or Suppressor.
  If you have your own muzzle brake or suppressor, this is what we charge to thread the muzzle of your barrel to fit. We need to know the thread pitch (i.e. 1/2 x 28, 5/8 x 24, etc) plus the length of the thread. If you send your brake along with your barrel, we'll be happy to install it for you at no additional charge. However, Do NOT Send Your Suppressor.
  Service Notes: This service custom threads and crowns the muzzle of your barrel (our 11° target crown) to the thread spec provided by you. Rebluing or other re-finishing is not included. Also, it does not include a thread protector.  Delivery time: 6-8 weeks.
