Barrel shortening

Hey team after recommendation for some one to reduce the length of my 870 clone, and have them rethread the barrel for chokes it came with.

Thanks

Nelson Collie does Rem Chokes so if it is a rem choke clone he may be able to help.

My reccomendation would be not to shorten it. It you are dead set on it it's probably easier to get another barrel or shotgun than rethread and move the bead on that one.
