The Mossberg 590 is a legendary pump-action shotgun, renowned for its reliability and versatility. Adding a heat shield significantly enhances its capabilities, particularly in situations involving rapid firing or extended use. This guide delves into the benefits, considerations, and practical aspects of owning a Mossberg 590 equipped with a heat shield.
Why Choose a Mossberg 590 with a Heat Shield?
The primary advantage of a heat shield on your Mossberg 590 is, unsurprisingly, heat protection. Rapid firing can generate significant heat, especially with heavier loads. This heat can:
- Discomfort: Make the shotgun uncomfortable or even painful to hold during extended use.
- Malfunction: In extreme cases, excessive heat can lead to malfunctions, potentially compromising your safety and operational readiness.
- Damage: Prolonged exposure to high temperatures can damage the firearm's finish and potentially internal components.
A heat shield acts as a thermal barrier, preventing this heat from transferring to the firearm's receiver and forend. This results in a more comfortable shooting experience, increased reliability, and prolonged lifespan for your shotgun.
Beyond Heat Protection: Added Benefits
While heat protection is the core function, a heat shield also offers several secondary benefits:
- Enhanced Aesthetics: Many heat shields are designed to improve the shotgun's aesthetics, adding a tactical or aggressive look.
- Improved Grip: Some heat shields incorporate textured surfaces or ergonomic designs, enhancing your grip and control.
- Accessory Mounting Points: Certain heat shields include Picatinny or Weaver rails, providing mounting points for accessories like lights, lasers, or grips.
Types of Heat Shields for Mossberg 590
The market offers various heat shields specifically designed for the Mossberg 590. They differ in materials, design, and features. Common materials include:
- Aluminum: Lightweight and relatively inexpensive, aluminum heat shields offer good heat dissipation.
- Steel: More durable and heat-resistant than aluminum, steel shields offer superior protection but add weight.
- Polymer: Lightweight and often less expensive than metal options, polymer shields are a viable alternative for less intense shooting scenarios.
Consider the intended use of your shotgun when selecting a heat shield material. For frequent high-volume shooting, a steel shield might be preferable, while aluminum or polymer might suffice for occasional use.
Installation and Considerations
Installing a heat shield on a Mossberg 590 is generally straightforward, often involving attaching it to the existing barrel with screws or clamps. However, always consult the manufacturer's instructions for your specific heat shield model.
Important Considerations:
- Compatibility: Ensure the heat shield is specifically designed for the Mossberg 590 model you own (e.g., 590A1, 590 Shockwave, etc.).
- Weight: A heavier heat shield will add to the overall weight of your shotgun.
- Length: Some heat shields extend beyond the barrel, potentially affecting how the shotgun fits in a case or scabbard.
- Legality: Check your local and state laws regarding firearm modifications.
Conclusion: Is a Heat Shield Necessary?
Whether or not a heat shield is "necessary" depends on your shooting habits and intended use. For casual shooters, it might be an unnecessary expense. However, for those who engage in frequent rapid-fire drills, competitive shooting, or tactical training, a heat shield provides significant benefits in terms of comfort, reliability, and firearm longevity. The added protection and potential aesthetic enhancements make it a worthwhile investment for many Mossberg 590 owners.
