Sub 2000 front nut removal

[golddigger14s]

How do I get the front nut off to put my suppressor on?

Mine unscrews easily…

If you bought it used the previous owner may have rockset it and the muzzle nut will have to be set in boiling water to loosen it. Then give a liberal coating of oil to prevent rust.
