Msbrg Heatshield 500/590 12ga

The Mossberg Heatshield for 500/590 12 gauge shotguns is a purpose-built thermal protection accessory designed to keep your support hand safe from barrel heat during extended shooting sessions. Compatible with plain-barrel variants of the Mossberg 500, 590, and Maverick 88, this heatshield mounts directly to the barrel, reducing accidental contact burns and improving weapon handling comfort during tactical operations, training drills, or field use where sustained fire is required.

Constructed to fit standard 12-gauge barrels, the heatshield reflects radiant heat away from the shooter's hand and forearm, a practical consideration often overlooked until experienced during real-world deployment or qualification courses. The lightweight design—just 0.5 lbs—adds minimal bulk while delivering measurable thermal barrier performance. Its compact profile (16 inches long, 3 by 2 inches in cross-section) maintains the shotgun's handling characteristics and does not interfere with typical shooting stance or manipulation.

This accessory is purpose-built for operators, LEOs, and serious shooters who run their 500 or 590 in patrol, breaching-ready, or training roles. Notably, compatibility is limited to plain barrels—it is not compatible with 590 7-shot models equipped with +1 extensions, 590 Shockwave platforms, 590A1 variants, specialized breacher barrels, or barrels featuring ghost ring sights. Verify your specific barrel configuration before purchasing to ensure proper fit and function.
