Cutting back a spare 20" barrel

[l2e]

I have a spare 20" COLT barrel that I would like to cut down to 10.5". Is this possible in relation to the location of the rifle length gas port? Or another question, what is the longest I can cut the barrel to if the barrel is cut right after (coming from the muzzle) the rifle gas port.

I hope that made sense?

eh, a rifle gas port is a little over 12". you can certainly cut to 10.5, but you'll be drilling a new gas port. not a big deal.

Or if the barrel is in decent condition you could sell it and buy the barrel you really want... Colt should bring good money...

HBAR or Gov profile?

does the barrel have the right diameter for a GB or FSB at the new gas port location?
