Factory Mossberg 590A1/500 12 Gauge Steel Action Slide Tube (6-1/2 Inch)

Here's a solid factory take-off or overstock part for your Mossberg shotgun.

It's a steel action slide tube, the component that the forend attaches to, specifically for 12 gauge models like the 590A1 and the 500 series.

It measures 6-1/2 inches.

This particular one is in excellent condition—practically new—but it might not be in the original sealed retail packaging.

It might just be the bare part ready to install.

It's genuine Mossberg hardware, made in the USA, so you know the quality and fit are right.

There's no wear on it.

If you're rebuilding a shotgun or swapping out a worn tube, this is a direct OEM-style replacement.

MPN isn't listed, but it fits 12 gauge 500s and 88s.
