Description

The Mossberg Barrel Heat Shield Kit is the factory-made answer for anyone running a plain, non-vent-rib 12 gauge barrel who wants both the vented military profile and a little insurance against a blistering barrel. After a fast string of buckshot, that barrel gets hot in a hurry, and this shield keeps your support hand clear so you can stay on the gun instead of nursing a burn. It's built by Mossberg to drop right onto your 500, 590, or Maverick 88 without any permanent gunsmithing.

What the Marinecote Heat Shield Kit Is Made Of

This kit combines glass-filled nylon and aluminum, which gives you a solid, rugged shield without piling weight onto the front of your shotgun. The Marinecote finish is the real standout here. It's a corrosion-resistant coating originally developed for saltwater and harsh-weather duty, so if your Mossberg sees boat time, duck blinds, or damp storage, this shield holds up better than a plain blued piece. The silver tone also gives your gun a distinct look that stands apart from the usual all-black setups.

Fitting the Heat Shield Kit to Your Mossberg

Installation is a clamp-on job that most folks handle at the kitchen table. The kit ships with mounting hardware, a spacer, and instructions, and you'll want a hex key and a small wrench on hand to start the screws before final tightening. A couple of tips from people who've done it: pay attention to the spacer sizing called out in the directions for your specific model, and don't crank the front retaining screws down too hard, since snugging them evenly does the job without stressing the clamp.

This shield is made for plain, thin-walled 12 gauge barrels only. It will not work with vent rib barrels, and it's not compatible with 590 7-shot models with the +1 extension, the 590 Shockwave, 590A1, 590M, breacher barrels, or ghost ring sight barrels. If your barrel is a standard bead-sight plain barrel, you're in the right place.

Frequently Asked Questions

Will this Mossberg heat shield kit fit my shotgun?

It's built for 12 gauge Mossberg 500, 590, and Maverick 88 shotguns with plain, thin-walled barrels that do not have a vent rib. It will not fit vent rib barrels, and it's not compatible with the 590 7-shot with +1 extension, 590 Shockwave, 590A1, 590M, breacher barrels, or ghost ring sight barrels. Check that your barrel is a standard bead-sight plain barrel before ordering.

Is the Marinecote heat shield hard to install?

Not at all. It's a clamp-on design that most people install at home in a few minutes with a hex key and a small wrench, and no permanent gunsmithing is required. The kit includes instructions and a spacer, so follow the sizing notes for your model and avoid over-tightening the front screws.

Does the heat shield actually keep the barrel cooler?

Its main job is protecting your support hand from a hot barrel rather than cooling the barrel itself. After running fast strings of buckshot, the barrel heats up quickly, and the vented shield gives you a safe surface to grip so you stay on the gun. Users report being able to hold their shotgun bare-handed right after running multiple rounds.

Why choose the Marinecote finish over blued or Parkerized?

The Marinecote finish is a corrosion-resistant coating designed for wet and harsh-weather use, making it a smart pick for boats, duck blinds, and humid storage. It also gives your Mossberg a distinct silver look that stands out from typical all-black tactical setups. Mossberg offers the same shield in blued and Parkerized if you'd rather keep things dark.
