With the exception of the 11-87 Super Magnum, all Model 11-87 receivers are basically the same. The barrel shipped with the shotgun will determine what can be shot from it. You can retrofit any right hand Model 11-87 barrel to any right hand Model 11-87 receiver within gauge.
In order to shoot field loads in a target shotgun you must fit it with a magnum field barrel. They are completely interchangeable and require no special training or tools to do the job. Refer to the Model 11-87 owner's manual.
You can view a list of replacement barrels through our online store at www.shopremingtoncountry.com.
