you don't need to get any parts down. all you are doing is shortening the bbl. i'd consider trying to trade for a carbine vs. the smith work.
remove the grenade launcher, that will shorten the OAL a few inches
Thanks, I thought any modification meant having to change parts.
So you think it's not worth the cost? How much do you think it would be? I saw some carbines today at the gun show for $350 and the other stuff was expensive, so maybe I could get one for $300?
