Should only take a few minutes. Have you loosened the grub screw?

Yes, that's what I mean. Believe it or not a gun came to me that had been worked on at a local airsoft store by an incompetent tech that did not remove the screw and the threads are now ruined. It's always better to be safe than sorry therefor I ask the simple, yet important, questions quite a lot.

Guys you have to watch out. There is another version of this barrel. If you want to shorten the barrel on this one, they are clockwise threads. I have 2 M4A1 barrels which are different than the ones shown and they have counter clockwise threads.
