How to Take Off the Forend on the Mossberg 88

Explore America's Campgrounds

Mossberg manufactures several different models of pump shotguns for sporting, law enforcement and military use. The pump guns -- such as the Model 88 -- are based upon similar designs that allow field stripping for cleaning and lubrication. The Model 88's forend slide is removed for cleaning, repair or replacement.
