Mossberg 500 Heat Shield Buyer’s Guide

Some people will argue that you don’t absolutely need a heat shield on a shotgun. Especially if you are going to be shooting a single slug or two deer hunting. Whereas range enthusiasts, competitive shooters, and some bird hunters will tell you that it’s an absolute necessity.

Assuming you have already thought this through and decided to pull the trigger on buying a new heat shield for your Mossberg 500 shotgun, there are a few things to keep an eye out for.

The Material Build Quality

Like all gun components, material build quality is a critical factor. When it comes to Mossberg 500 heat shields aircraft-grade aluminum and steel are the two materials most commonly used by manufacturers. 7076-T6 aluminum has a reputation for absorbing shock and recoil. It also has good ductility, toughness, and superior resistance to metal fatigue. Though it’s certainly not the only material worth considering. Especially with how it can drive up the price.

The Finish

For many, shotgun heat shields also have aesthetic value. As you are shopping for the right heat shield for your Mossberg 500, take a moment to consider the finish and how it will match the overall look of the gun. Most people prefer a matte black or matt blue finish to blend in with the Mossberg 500 barrel, though they certainly aren’t the only finishes worth considering.

Though there are Parkerized finishes and marinecoat finishes to consider. These additional treatments help protect the heat shield. Marinecoat is often a priority for people who hunt waterfowl in estuaries and saltwater wetlands. Though these special finishes do tend to increase the heat shield’s price point.

The Ease Of Installation

Some Mossberg 500 heat shields are easier to install than others. If your gunsmithing skills are modest or your tools are limited, you might want to prioritize a heat shield with a reputation for being easy to install. Otherwise, you might want to secure the services of a qualified gunsmith to make sure the install is done right the first time. Especially, if you have your eye on something like an innovative free-floating heat shield.
