What are the Legalities of Converting My Mossberg 500 to a Tactical Shotgun?

If your shotgun meets the federally mandated minimums for the length of the barrel and the shotgun’s overall length, there are no legal restrictions. Specifically:

  • The barrel can be no shorter than 18 inches from the breach to the muzzle.
  • The overall length of the shotgun with the stock extended must be at least 26 inches.

If your shotgun meets these minimum requirements, there is not permitting, licensing, or taxing required

What other Accessories Might I want on a Tactical Shotgun?

Generally, people convert their Mossberg 500 shotguns to a tactical version to use as home defense or personal defense firearms. When choosing additional options or accessories, you should consider how you may use the shotgun. Some of the more popular accessories added to converted shotguns include:

  • Flashlights – A flashlight is a natural addition to a tactical shotgun. Most home defense encounters occur at night. Having a light attached to your shotgun frees your hands to maneuver, aim and fire the shotgun if the need arises. Trying to hold a flashlight in one hand and fire a shotgun with the other is a recipe for disaster.
  • Laser Sight – There are several good laser sights designed to attach to your Mossberg 500. The advantage of a laser sight is instant recognition of a target. When properly installed and sighted, you can be sure that your shotgun is pointed at that target wherever the laser dot appears.
  • Shell Holders – Shotguns, especially those with shorter barrels, carry a limited number of shotgun shells in the tube. Having additional shotgun shells in a holder attached to the shotgun keeps your extra ammo close at hand.
  • Slings – Most tactical shotguns have sling swivels, or quick detach sling mounts. Having a sling allows you to carry your shotgun easily and safely while keeping one or both hands-free for other jobs.

The Tactical Conversion – Pick your Style and Go!

Doing a tactical conversion on a Mossberg 500 is a relatively easy task. Most kits don’t require any gunsmithing or fitting. A tactical conversion can turn your standard Mossberg 500 into a formidable and more efficient home defense weapon.
