backitup83@Yahoo.com turn the screw at the front of the slide.It will unscrew only so far. once it is loose turn the barrel either right or left,once it is away from the center of the tube it should lift out. There are threads and something like keys on each side of the barrel,once they line up it should lift out. At least that is how it is on the 30 E series.
hire it done.
the large magazine cap screw has to be unscrewed, after which the barrel simply rotates and slides off the front of the shotgun.
Yes, you can remove the barrel of a model 66 Shotgun!
with a hacksaw
Who made it? Is it a shotgun, rifle or handgun?
Unscrew the Magazine cap and remove the barrel. There is a clip/ring at the end of the magazine tube. Revove the clip and the spring and plug will come out. Replace the spring and reassemble.
with a torch
If it is a double, remove barrel and you will see it along with serial #.
you cannot remove it. it is all in one with the receiver frame
remove the magazine cap by unscrewing, then the forearm will slip off. then pull the barrel off.
take out the scew on the bottom side of the barrel
You can clean it, but you cannot remove the pits. If it is badly pitted, you will need to have a gunsmith bore and reline the barrel or replace it.
