Mossberg 500 Tactical Conversion Kit Buyer’s Guide

Mossberg 500 tactical conversion kits can be as sparse as a buttstock and a forend. Though some include things like side saddles cheek risers or are compatible with a rail system to add accessories. The following are some things to consider when looking for the best Mossberg 500 tactical conversion kit for your planned build.

The Buttstock

A lot of the best Mossberg 500 tactical conversion kits come with a stock that is specially designed to absorb shock while reducing the effects of recoil on accuracy. An adjustable buttstock also lets you customize the draw length to your arms. A particularly long-armed shooter might prioritize a tactical conversion kit where the buttstock can be extended out to 16-inches, whereas a shooter with shorter arms might prioritize one that is set as short as 11-inches.

A Side Saddle Or Shell Carrier

Side saddles are designed to hold extra shotgun rounds. Most have a minimum capacity of four shells. Though some side saddles may have a capacity of six shots or more. When choosing the best side saddle for your build, you might want to consider the reloading time you need for additional rounds. One that is attached to the side of the receiver tends to easier to reload quickly as they are closer to the ejection port or the shotgun’s magazine.

Other Factors To Consider In A Tactical Conversion Kit

When you are shopping for a tactical conversion kit there are a few things to consider. Especially if you are on a somewhat limited budget, or you have a specific vision in mind.

Material Build Quality

Just like everything in the world of firearms, material build quality is going to translates into long-term durability. In the real world, you might only need to use your tactical-built Mossberg 500 shotgun once or twice for home defense. Though in simulation and tactical training, home defense shotguns can log a lot of wear and tear over the life of the weapon.

The last thing you want is for your tactical shotgun needing frequent replacement parts just for training purposes. So, while you might be on a limited budget at the moment, this isn’t a place to skimp. If you do have a little more budget to work with, and you plan on frequently training with the tactical shotgun to stay sharp, then springing for one with a reputation for superior material build quality is likely going to save you money in the long run.

In general, polymer buttstocks and glass-reinforced components are popular. These materials have a reputation for being able to suffer a lot of wear and tear while also offering superior weatherproofing. Though there certainly are some over-molded rubber components that offer reasonable durability at a lower price point.

Rail System Compatible Forend For Accessories

Some operators plan their tactical conversion to include accessories like a flashlight, strobe light, optics, or lasers. It’s especially handy when you consider that a lot of home invasions that occur at night. So, something like a flashlight makes sense to see what you are shooting at. The last thing you want is to risk a shot in the dark when other family members might be up and reacting to the sound of an intruder forcing their way into your home.

A tactical conversion kit that comes with a rail system or is compatible with a rail system like Picatinny will make it easy to add these accessories without having to make modifications.

Ease Of Installation

If you are contemplating a Mossberg 500 tactical conversion kit, and you aren’t experienced with gunsmithing, then installation might seem intimidating. If this is the case, then you want to prioritize a kit with a reputation for being easy to install.

Thankfully, there are a lot of good kits out there that most people with a modest amount of mechanical sympathy can install on their own. Though if you’re not comfortable with this, then there’s no harm in seeking the services of a professional gunsmith.

Frequently Asked Questions

Are There Any Federal Regulations Concerning A Mossberg 500 Tactical Conversion?

As long as the shotgun in question is technically classified only as a non-folding shotgun stock, then there are no federal permits, regulations, or fees associated with using a tactical conversion Mossberg 500. The ATF also requires that your Mossberg 500 barrel be 18-inches or longer.

Is A Flashlight With A Strobe Feature Effective?
Some people argue for and against the effectiveness of a tactical strobe light. Most people who argue in favor of one will tell you that it’s not a deal-breaker if a conversion kit doesn’t have one or isn’t compatible with a rail system to accommodate one.

Any dazzling effect on an intruder is ultimately short-lived. Though the chance to blot out their vision or compromise their night vision with a high-lumen count flashlight or strobe light could buy you valuable time to reload in a real-world tactical situation.

Do I Need A Shell Carrier Or Side-Saddle?

While a side saddle or shell carrier is handy for quick reloading, some would argue that it’s unnecessary for a real-world home defense tactical shotgun. It’s when you start to think in terms of professional tactical use that it starts to rise higher on the priority list.

Are All Tactical Conversion Kits Compatible With A 590?

A lot of Mossberg 500 tactical conversions kits are compatible with a 590, but not all. If you are planning a tactical conversion with a 590, then you might want to double-check with the manufacturer’s specs.

Are There Tactical Conversion Kits For 20-Gauge Mossberg 500 Shotguns?

There are a few tactical conversion kits on the market that are compatible with a 20-gauge Mossberg 500 shotgun. Though by and large, most are only compatible with 12-gauge shotguns.

Conclusion

If you have a Mossberg 500 that you are thinking about converting into a tactical shotgun or you are planning a custom-built tactical weapon, then there certainly are a lot of interesting options to fit just about any budget.
