Gaylon, I don't see why you couldn't put a 22" barrel on this firearm. If you can find one or have one made. I would talk to a competent gunsmith. I do not know how this 18" barrel is set in the receiver.

you will need a custom Gunsmith and you are looking at a High cost try these guys https://www.fulton-armory.com/M14-M1A-Services.aspx

Gaylon, As randy i mentioned Fulton Armory is in the M1A barrel business. Good place to start.
