cutting down barrel

[monkeywrench]

Can a barrel with chrome lining be cut down and not be hurt?

[Buck]

Well it may sting a little... But yes...

No problem with cutting them. Chrome lining isn't like bumper chrome.

Does the gas hole size need to be changed ?

Does the gas hole size need to be changed ?

It depends on how far you're cutting it. Many times a 16" bbl cut to 14.5" won't need a change and many times a 20" cut to 18" won't need a change.

If you're going from 16" to 10.5" yes you will need a change unless you're only shooting suppressed.

For barrel cutting, threading, crown and gas port work I use and recommend Randall at www.ar15barrels.com
