The Mossberg Maverick 88 is a 12 gauge pump action shotgun manufactured by O.F. Mossberg & Sons. It's a lower cost version of the Mossberg 500. Most of the accessories are compatible with the Mossberg 500 except for the forearm assembly.
The Maverick line of shotguns are assembled in Eagle Pass, Texas using some parts manufactured outside the USA, mainly from Mexico; which contributes to their relatively lower cost in comparison to the Mossberg 500 series of shotguns, which is entirely domestically manufactured and assembled at the Mossberg factory.
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 Maverick 88 does not come equipped with any sling mounts, as the Mossberg 500 series do.
Maverick 88 shotguns feature a trigger guard-mounted cross-bolt safety as opposed to a top tang safety, which is used on the Mossberg 500 series.
Early Model 88s were equipped with a single slide rail, but this was updated to a dual slide rail in 1990. Also the Maverick 88 does not have a receiver top pre-drilled and tapped for a Weaver scope mount rail.
Maverick 88's are factory finished with steel bluing only, whereas Mossberg 500s have factory blued, nickel plated or parkerized options.
There are two basic models of the 88, the Maverick 88 field and the Maverick 88 security. The 88 field comes with a longer 28" vent-rib barrel, whereas the security comes with an 18-1/2" or 20" non-vent-rib barrel. The 88's have a cartridge capacity of 5 in the tube magazine and 1 in the chamber and cannot have their magazines easily extended without machining. Magazine capacity is further limited, if loading "3 shells, to 4 in the tube magazine and 1 in the chamber.
The Mossberg Maverick comes from the factory with a black synthetic stock and forend. Sling swivels are not included, however they can be installed to allow the use of a sling.
The Maverick 88 uses 12 Gauge 2-3/4" or 3" shells.
