Description
The Mossberg 590 Shockwave 12GA is a shotgun chambered in 12 Gauge. This model is configured as described in the title.

Mossberg 590 Shockwave 12GA Overview
The 590 Shockwave is a compact 14-inch-barrel pump-action firearm with Mossberg’s signature bird’s-head Raptor grip, shaped to reduce felt recoil. Its short overall length makes it maneuverable in tight spaces for home defense and vehicle use.
Design and Features
It shares the features that made Mossberg pump-actions famous: ambidextrous top safety, dual extractors, positive steel-to-steel lockup, twin action bars, and a smooth anti-jam elevator.
Handling in the Field
Mossberg shotguns are built to be dependable year after year with simple maintenance. This model mounts naturally and swings smoothly, and it is ready for the field, range, or home defense right out of the box.
Action and Trigger
The pump action is fast and reliable with nearly any load. Rack the forend fully for each shot, and use the top-mounted safety, which works for left and right-handed shooters.
Sights and Optics
Mount the optic of your choice with quality rings or a mount, and zero it with the load you plan to use.
The 12 Gauge Cartridge
The 12 Gauge is the most versatile shotgun chambering, with loads for everything from clays and birds to buckshot and slugs.
Setup and Accessories
Set your shotgun up for its job: hunters will want a sling and a few choke tubes, clay shooters may add a recoil pad, and a home-defense setup benefits from a weapon light. Pattern every load and choke combination you plan to use.
Ownership Tips
Read the owner’s manual fully before your first range trip, and keep the manual, box, and receipt with your records for warranty service and resale. Unload the shotgun and confirm it is empty before cleaning. Field-strip it according to the owner’s manual, scrub the bore with a brush and patches, and wipe carbon from the action and choke threads. Apply a light coat of quality gun oil to the contact points, and wipe the exterior with a lightly oiled cloth before storage.
