How to Replace the Barrel in a Mossberg Shotgun

O.F. Mossberg &Sons crafts quality shotguns that are rugged and inexpensive. Mossberg has been the choice of the U.S. military, private security firms and hunters worldwide. The barrels on Mossberg shotguns are relatively easy to replace, but they are not interchangeable between models. Be sure that your new barrel is for the same model and gauge as your old one. As with any firearm, check to be certain that the shotgun is unloaded before you start working on it.
