What’s in a Tactical Conversion Kit?

Your tactical conversion kit will come with all kinds of accessories. However, one brand may have included some parts that otherwise may not be found in other kits from a different brand. But, you will be able to find some parts and accessories that are common and can be found in all tactical conversion kits. Here’s what you’ll find:

Barrel

One of the things that you’ll be surprised to see is a shotgun barrel. These barrels will measure in at around 18 inches. This barrel length is ideal for those who want to use their shotguns for home defense or tactical purposes. Plus, your rounds will be able to travel faster and eject from the shotgun much quicker than it would if a 20-inch barrel was installed on it.

Stock

Of course, a buttstock is typical for tactical conversion kits. Especially a stock designed to absorb any shock associated with recoil. At the same time, you want a stock that is also designed to reduce as much recoil as possible. You can expect a stock made from high-quality materials that are designed to hold up to any usage in a tactical conversion kit.

Side Saddle

A side saddle is designed to hold any additional shotgun rounds. These typically have the capacity to hold up to four shells. However, there are some side saddles that may have a capacity of six shots or more.

Either way, you'll want a reliable side saddle that will allow you faster reloading each time you need additional rounds. Side saddles attach to the side of your receiver for easier access and due to its close proximity to the ejection port or magazine port for quicker reloading.

Flashlight

A flashlight will definitely come in handy in a home defense situation. Especially when home invasions tend to happen during the night and everyone in your house is sleeping. You’ll need to be able to navigate around your home and also be able to get a good look at your assailants prior to using your Mossberg 500.

Some flashlights may also have a strobe feature that can temporarily disorient your attacker. This may come in handy in the event that your shotgun can no longer function or when reloading. This is especially effective if you’re dealing with one attacker.

How to Choose a Tactical Conversion Kit

There are some things that you need to focus on while you’re looking for a good tactical conversion kit. Whether you’re on a budget or have some money to play with, it’s always important to find a kit that will allow you to convert your Mossberg 500 shotgun to a tactical force to be reckoned with. Here’s what you’ll need to keep watch for as you’re searching for a kit of your own:

What’s Included?

Some of the things you need to look out for are the accessories that are included in the list above. A barrel will obviously be included in the mix, along with a side saddle, a buttstock, and a flashlight.

If you think you're better off without one of these parts, that's entirely up to you. But these will typically be found in most tactical conversion kits. Other additional accessories may also be included as well. This will depend on the brand name that creates these kits.

Material

It's important to know what type of material is used to construct the parts. The main reason for this is durability. You want your tactical conversion kit to include parts that are super strong and will last you a long period of time.

The last thing you want to do is use your shotgun and end up having to constantly replace pieces and parts that fail. That, of course, means spending more money. You should do your wallet a favor and save yourself the financial headaches.

A material to look out for is polymer. Polymer is designed to be tough and durable. The same goes for steel or aluminum (if barrels are included in the kit). You want something that can take a beating and is easy to clean.

Installation

If you're considering the idea of using a tactical conversion kit, you'll want to find one where installation is a breeze. This means you don't need any gunsmithing skills at all to install it. Nor will you need to enlist the services of a professional to install the entire kit. Some of these kits include buttstocks and other accessories that will take minutes to install and require less tool usage.

Included in the kit is an 18-inch barrel, a magazine with a capacity of either five or ten rounds (your choice).

You’ll be glad to have a kit that includes a barrel that is the perfect length for a tactical shotgun, plus enough rounds for you to use in a situation where you need them the most.

Pros

  • Very Reliable Performance
  • Fits Perfectly on Most Mossberg Shotguns
  • Excellent for Home Defense and Tactical Purposes

Cons

  • Some Have Needed to Sand Down Some of the Parts to Ensure a Proper Fit

Next, we stay with the Adaptive Tactical brand. This time, we present the Venom-SE Shotgun Magazine Conversion Kit. The question we begin with is what is the difference between this and the other Adaptive Tactical Venom conversion kit that we just reviewed?

For one, this comes with a magazine with a ten-round capacity. You have no choice but to get a magazine with the ability to hold ten rounds. What’s also included is a buttstock, forend with the action bars, magazine tube, barrel clamp, and some additional accessories that will put this bad boy to work.

Aside from what’s included, this kit is designed to give your shotgun the best reliable performance. You’ll have an easier time feeding your shells through and be able to get your shots off a lot quicker. The number one thing you’ll want in a home defense or tactical situation is a Mossberg 500 that can operate with such quickness, smooth functioning, and unrivaled speed as this kit allows.

If your goal is rapid reloading and faster shooting, you’ll be pleased with the Adaptive Tactical Venom-SE shotgun magazine conversion kit. In fact, this may be one of the more affordable tactical kits on the market. But if the price is not more to your liking, be sure to check out the next conversion kit that we will be reviewing.

Bottom Line

While this may be an alternative to the other Adaptive Tactical conversion kit, this kit, in particular, is designed for those who want that tactical look and feel for their Mossberg 500 shotgun. What you'll get out of this is better functioning, which also means faster, smoother reloading. And that means more time on your side when you're in a situation where you have to fend off your attackers in a home invasion.

This kit may potentially save your life if you choose this for your Mossberg 500. So if you're looking for a kit that will give you an almost unfair advantage against home invaders, this is likely the best possible option.

Pros

  • Easy to Install
  • Reloading Time is Insanely Quick
  • Best Mossberg 500 Tactical Conversion Kit for the Money

Cons

  • Won’t Fit with Mossberg 20-Gauge Shotguns

Now, we'll turn our attention to yet another Adaptive Tactical kit that will best fit your budget. This comes with a ten-round box magazine that will be set and ready to go once loaded. Just slide it into the magwell, close the action, and it is go-time.

Not to mention, you'll get a magazine that is not only reliable in feeding but will allow you to reload your shotgun in the fastest time possible. If you're able to quickly reload in a high-stress environment like a home defense situation, you're in business. And, it will put you at an advantage over an attacker who is dumb enough to bring a knife to a gunfight (or a pistol that won't be as effective as they first thought).

Also included in this kit is a buttstock made from polymer designed to reduce recoil and absorb a good deal of shock. You need to reduce a good amount of recoil so you can be able to better control your shotgun. Lose control of your shotgun and your shot won't be as deadly accurate.

The accessories included in this kit are pretty much the same as the other Adaptive kit from earlier: forend with action bars, buttstock, grips and clamps, magazine tubes, and more. If you're looking to build a tough-looking shotgun with the ability to function as a tactical machine, you'll want to invest in this kit. In fact, this is the product you'll need if money is not so much an issue, but you want to stay within your means.

Bottom Line

This tactical conversion kit is not a “you get what you pay for” version. You definitely get more than you pay for, especially with the accessories that come included. If you’re looking for a product that will allow better reliability and the fastest possible reloading time, you may want to look at this Adaptive Tactical kit a little bit further. You won’t worry about breaking the bank purchasing this. But even if money isn’t an issue, this should not be written off as a cheap, low-quality offering.

Pros

  • Very Easy to Install
  • Recoil Reduction is Considerable
  • Fits Either 12-Gauge or 20-Gauge Shotgun Without Issues

Cons

  • None

Now, we’ll turn our attention to the Phoenix Technology Kicklite Tactical Buttstocks. If you’re looking for a buttstock that is designed for tactical usage and will also be able to reduce the amount of shock produced by recoil, then you’ll probably enjoy this buttstock.

Your greatest advantage using this will be the greater control you’ll have over your shotgun. This means more accurate, precise shots. On top of that, your follow-up shots will be quicker and you won’t have to experience a whole lot of fatigue.

The good news about this buttstock is that it fits Mossberg 12-gauge shotguns. Even better news, this also fits 20-gauge Mossberg shotguns. No matter which gauge you use, you’ll have a reliable item that you can use as a tactical upgrade.

This is an easy to install product that is designed to get the job done, not only in a tactical or home defense situations, but in any application that requires the use of a reliable, powerful shotgun like the Mossberg 500.

Bottom Line

A good buttstock is one good way to upgrade your shotgun and make it a tactical force to be reckoned with. If you’re upgrading it one part at a time, you’ll probably want to choose this one in particular before finding other parts that you’ll need to upgrade the gun as a whole.

Pros

  • Installs in Minutes
  • Fits Shotguns With 7-⅝ Assembly
  • Fits Most Mossberg 500 Shotguns

Cons

  • Will Not Fit Mossberg 500s With a 6 ½” Action Tube Assembly

Both are made from high-quality materials to ensure that they will last you a long period of time. These are lightweight accessories that won’t add on any additional weight to your gun. This will best fit your Mossberg 500 shotgun if you have a 7-⅝” assembly.
