Maximize Your Shotgun's Capacity with GG&G Mag Tube Extensions

The GG&G Mag Tube Extension allows you to add more capacity to your favorite shotgun! This model is compatible with 12 gauge Mossberg 590 shotguns. These magazine tube extensions are available in both +2 round and +3 round versions. The +2 round extension protrudes 2.25" past the muzzle when used with 18.5" barrels, and the +3 extension protrudes approximately 4.5" past the muzzle when used with 18.5" barrels. The end cap can be removed to facilitate cleaning and allow for the addition of a magazine plug. Each extension tube is machined from aluminum and the extension nut is machined from solid bar stock steel. Additionally, each extension includes a new extended length magazine spring in order to ensure reliable function.
