Mossberg 500

The Mossberg 500 is one of the most widely used shotguns in America — by hunters, homeowners, and law enforcement. A reliable, affordable pump with one of the largest aftermarkets ever built around a shotgun platform.

Mossberg 500 with nickel barrel and oversize safety.

The Mossberg 500 has been in continuous production since 1960. It is a proven pump-action with a tang-mounted safety, dual extractors, and a track record in every application from duck hunting to home defense. The aftermarket for the 500 is second only to the Remington 870.

We carry Mossberg 500 parts and accessories focused on what actually improves the platform — extensions, followers, springs, shell carriers, and slings — all selected for correct fitment.

FAQ

What magazine extensions fit the Mossberg 500?
The Mossberg 500 uses a specific magazine tube thread. Extensions must be 500-compatible — not interchangeable with Remington 870 or Winchester platforms. We carry 500 extensions adding 2 to 4 rounds depending on the model. Always replace the spring when extending the tube.
What is the difference between the Mossberg 500 and 590?
The 590 is Mossberg's heavy-duty version designed for military and law enforcement use. Key differences: the 590 has a metal trigger guard and safety (vs. polymer on the 500), a heavier barrel, and a different magazine cap design. Most accessories are interchangeable between the 500 and 590, but verify fitment.
Does the Mossberg 500 have a good aftermarket?
Yes — the 500 has one of the largest aftermarkets of any shotgun platform. Extensions, stocks, slings, shell carriers, optic mounts, and more are widely available. This is one of the reasons the 500 remains popular for both hunting and defense builds.
What follower should I use in a Mossberg 500?
The factory Mossberg 500 follower is generally reliable, but an aftermarket follower in a bright, high-visibility color makes it easier to visually confirm an empty chamber. It also reduces the chance of tilt-induced feeding issues. This is an inexpensive upgrade worth doing on any 500 used for defense.
