1. If the barrel was less than 16" it had a pinned and brazed flash hider or compensator on the barrel that was removed. If it is presently less than 16" do not put it on your lower! Federal violation! without having the stamp for an SBR.
2. Or it was a Brady Bill commercial market era gun 1994-2004 which was what they called a Post Ban Gun which had to have the muzzle break pinned and brazed as was required, which has been removed?
It never the less had a pin removed and the barrel is undercut so threading it for any traditional flash hider or muzzle break is not possible. You will rather have to have a new unit brazed or pinned on it. Or as mentioned previously get a new barrel.
The Constitution is not an instrument for the Government to restrain the people. It is an instrument for the people to restrain the Government!
Today, we need a nation of Minutemen, citizens who are not only prepared to take arms, but citizens who regard the preservation of freedom as the basic purpose of their daily life and who are willing to consciously work and sacrifice for that freedom."
-- John F. Kennedy
