the 500A "synthetic stocked guns" do not have a removable fore end that can be replaced as easily as the wood stocked model 500. The fore end is pinned in place and in order to replace the factory fore end you must also replace the action bar tube with the other type that just uses the fore end nut to hold it in place. All other parts and accessories (barrels included) are interchangeable as far as I know.
i have a 500A its old school camo synthetic was recently thinking of changing the stock to an adjustable ati, is it gonna be possible?
