We have recently retired and will be traveling around the country in our motorhome(when the travel bans are lifted). I have a 16 gauge Remington 870 Wingmaster that I want to carry in the RV. It has a 28" barrel that will be very difficult to use in the confines of an RV. I do not want to shorten this barrel as I do not want to diminish the value of the shotgun. I would like to find an 18" to 20" barrel to replace the longer one. A quick search online comes up with many 20 gauge barrels but no 16 gauge. I am hoping someone here will be able to help me locate one. Thanks in advance for any help you folks can provide.
