The Mossberg 590A1 with an 18.5-inch barrel is a popular choice for home defense and tactical applications. Its compact size and maneuverability make it ideal for close-quarters combat, but the shorter barrel can lead to increased heat buildup during rapid firing. This is where a heat shield becomes a relevant consideration. This article will explore the benefits, drawbacks, and options for adding a heat shield to your Mossberg 590A1 18.5" barrel.
Why Consider a Heat Shield for Your Mossberg 590A1?
A heat shield is a device that attaches to the barrel of a firearm, acting as a thermal barrier between the hot barrel and the shooter's hand. While not strictly necessary for short bursts of firing, a heat shield becomes increasingly beneficial during extended shooting sessions or rapid fire, offering several advantages:
- Reduced Barrel Heat: The most obvious benefit is the reduction in heat transfer to the user's hand. This significantly enhances comfort and control, especially during high-stress situations.
- Improved Grip: A heat shield can provide a more comfortable and secure grip, even when the barrel is hot. Some heat shields are designed with textured surfaces or ergonomic features to further enhance grip.
- Increased Accuracy: A cooler barrel can contribute to improved accuracy by minimizing heat-induced barrel expansion and potentially reducing recoil-induced shifts in point of aim.
What are the Drawbacks of a Heat Shield?
While heat shields offer several advantages, it's important to weigh the potential drawbacks:
- Increased Weight: Adding a heat shield inevitably adds weight to the firearm, slightly impacting its maneuverability.
- Potential for Interference: Depending on the design and the accessories attached to the shotgun, a heat shield might interfere with the operation of other components, such as certain sights or lights.
- Added Cost: Heat shields are an additional expense, and finding a high-quality, well-fitting shield can require some research and investment.
Do I Really Need a Heat Shield for my 18.5" Mossberg 590A1?
This is a subjective question. For occasional use or defensive scenarios involving limited bursts of fire, a heat shield may not be strictly necessary. However, if you anticipate extended shooting sessions, rapid fire, or training exercises involving numerous rounds, a heat shield can dramatically improve your shooting experience and potentially even enhance accuracy.
What are the Different Types of Heat Shields Available?
Several types of heat shields are available on the market, each with its own features and advantages:
- Aluminum Heat Shields: These are common due to their lightweight nature and relative affordability. They offer good heat dissipation.
- Steel Heat Shields: Steel heat shields are more durable and resistant to damage but are considerably heavier than aluminum counterparts.
- Polymer Heat Shields: Polymer heat shields are lightweight, impact-resistant and can come in various colors. However, they may not offer the same level of heat protection as metal shields.
How do I Choose the Right Heat Shield for my Mossberg 590A1?
When selecting a heat shield, ensure it's specifically designed for the Mossberg 590A1 with an 18.5-inch barrel. Check reviews and compare different brands to find one that fits well, is durable, and provides the level of heat protection you need. Consider the material, weight, and any additional features, like ergonomic grips or Picatinny rails.
Can a Heat Shield Affect the Accuracy of my Shotgun?
While a heat shield itself doesn't directly affect accuracy, the reduced barrel heat it provides can indirectly improve accuracy by minimizing barrel expansion and the resulting shift in point of aim. However, this effect is often minimal and may not be noticeable to all shooters.
Will a Heat Shield Make my Shotgun too Heavy?
The added weight of a heat shield will depend on the material and design. Aluminum heat shields are significantly lighter than steel ones. The weight increase is usually manageable, but it's a factor to consider, particularly if you prioritize lightweight maneuverability.
Where Can I Buy a Heat Shield for my Mossberg 590A1?
Various online retailers and gun stores sell heat shields for the Mossberg 590A1. Always verify compatibility before purchasing. Look for reputable vendors with positive customer reviews. (Remember: I cannot provide specific links to retailers.)
