Not very easily. The barrel is not designed to be removed by the user. With the gun empty, work the bolt to cock the hammer. Drift out the two pins that retain the trigger guard assembly and that can be removed. No further action dis assembly is advised.

No. The Model 66 does not have user-interchangeable barrels. Your existing gun could be modified by shortening the barrel, adapting for choke tubes and installing rifle sights. sales@countrygunsmith.net
An automatic shotgun from Sears Roebuck would top out at around $200.
