Question: will a mossberg 500 stock fit a maverick 88

Answer: Yes, The trigger groups will not interchange between Maverick 88 and Mossberg 500 models, but the majority of other parts, including barrels, stocks, and magazine tubes, will (the barrel and magazines must be the same length). Maverick 88s do not come equipped with any sling mounts, as the Mossberg 500 series does.
