Dfend, the Maverick 88 is the Mossberg 500 on all but 2 parts. The reciever and the trigger group/ safety are the only differences between the two. ANy stock for the m500 will fit the 88. Same with barrels. When I gave my maverick to a friends kid, it went with 2 mossberg 500 barrels that I picked up for it over the 17 years I owned it, and they fit like a glove. Pick up the parts you want and go for it.
