Due to differing state gun laws across the United States not all parts are available for sale to all states. John Masen Company can not ship orders outside the United States.
It is the purchasers responsibility to know the current gun laws of their respective states. Currently, muzzlebrakes can not be shipped to the state of California. With the current wave of gun legislation more restrictions are likely on the sale of gun parts to various states. Please contact your local or state government to ensure that you are in compliance with all local and federal gun laws. We appreciate your assistance in this matter.
