Picatinny vs. Weaver Rails
There are two kinds of gun rails: Picatinnys and Weavers. These are accessories typically found on shotguns and rails. One thing you’ll probably notice is that the profiles look almost identical to each other. But make no mistake, they both have distinct differences. To know more about them, let’s break down what each is and how they differ from each other.
Let’s take a look at the recoil grooves of a Picatinny rail. The grooves are typically measured at .206” in width and are measured at approximately .394” in center-to-center width. A Picatinny is more of a military-style rail. In fact, in the mid-1990s, the military began utilizing Picatinny rails for the use on their guns.
The groove measurements of a Weaver rail will be .180” in width. However, the center-to-center width measurements are inconsistent. One Weaver’s measurement can differ from another. It is for this reason that the Weaver is not considered to be an interchangeable rail.
Pros and Cons
So what are the pros and cons of each type? The Picatinny rail will fit accessories like scopes that are compatible with the rail itself. Obviously, the major con is that it won’t fit accessories that are designed for the Weaver rail.
Likewise, the same can be said about the Weaver rails. Accessories designed for the Weaver will fit on the rail, but won’t take on Picatinny accessories. This should be something to remember as you are installing a scope or anything else on your Mossberg 500.
A Picatinny rail may also throw off your scope’s aim. More specifically, this is due to the lack of windage adjustment.
Another disadvantage of the Picatinny is the weight, despite the fact that most manufacturers sell lightweight versions of the rail itself.
Weaver rails have a disadvantage of the slots being irregularly placed. This will make the installation of a one-piece rail a challenge. This is not overly surprising, considering that the center to center measurements and the groove measurements are a little smaller than that of the Picatinny.
How to Choose a New Rail For Your Mossberg 500
Of course, grabbing a rail for a Mossberg 500 off the shelf or hitting the "buy now" button may seem like a tempting option to get it out of the way. But this isn't the smart thing to do when choosing a new rail.
The reason is that low quality, cheap products are flooding the market. It would take a little time and a bit of detective work to make a final decision on which is best for you. In order to know what to choose in a rail, there is no one better to tell you than the past buyers themselves.
Here are a few things that they recommend for you to look at:
Picatinny or Weaver
Some like a Picatinny rail. Others like a Weaver rail. If you're a first-time buyer, this may be something that will put you in an indecisive position. However, if you have a scope or any kind of accessory for your Mossberg, then the choice may be easy enough. See if your accessory is compatible with either of the two rails or both.
We always place quality as a high priority when it comes to looking for a new accessory for guns. The reason is that we want it to last a long time. The last thing you want to do is throw money out the window because you bought rails that keep breaking. The important thing is to look for products made from high-quality materials. These materials include, but are not limited to, aluminum, steel, and polymer.
The installation process for most of these should be easy enough. You’ll need to find a rail for your Mossberg 500 that will be easy to install and won’t require you to employ the services of a professional gunsmith. As mentioned before, the one piece Weaver rails may be a bit of a challenge to install because of the groove measurements.

It has rail slots designed to allow easy installation of accessories like scopes. This is also flexible for any eye relief adjustments needed to ensure that you can get a better view through your scope without dealing with any issues that can be caused by other products.

The ability of it handling Picatinny or Weaver rail-compatible accessories is what stuck out the most. Most importantly, this is a very tough product that can last you a pretty good while.

Best Quad Rail:

This is not only the best for tactical situations, but you can also pair any accessory with it. If you have a Mossberg 500 or 590 shotgun for the use of home defense purposes, you'll probably need a rail like this, because you can add some other tactical style accessories to this without issue.

ERGO KeyMod Tri-Rail
Next, we have the ERGO KeyMod Tri-Rail. Why do they call it a tri-rail? Because you have keymod rails located in three different places. Picture it like a clock for a moment. You have rails located at the 3, 6, and 9 o’clock positions respectively. These are designed for you to easily install any accessories you wish to make your Mossberg 500 a force to be reckoned with, both out in the field and out on the range.
This is a low-profile, super durable rail that is constructed of high-quality aluminum. Not to be outdone, this is also finished with a black anodized hard coat for added durability. If you’re looking for a product that will allow you to add on multiple accessories, you’ll probably want to give the Ergo KeyMod Tri-Rail a closer look.
The main thing that stood out with this product, of course, is the tri-rails themselves. While some rails have 13 slots for the accessories you need for your Mossberg, the tri-rail allows the accessories to be spread out and uncluttered (like you would probably see in a straight rail).
With that said, this is a super durable rail that is designed for whatever purpose your Mossberg 500 serves. Plus, this will allow your gun to be a little more ergonomically-friendly. If that's something you look for in a rail, then the Ergo KeyMod Tri-Rail might be right for you.
Best Tactical Rail:
AIM Sports Inc M-Lok Modular Rail
If you're looking for a great tactical-style rail and haven't found the Black Aces rail to be as impressive, then you'll want to have a look at the AIM Sports Inc M-Lok Modular Rail.
One of the things that stood out upon looking at this is the six shell holder that comes with it. If you don't have anything like a side saddle or a sling with shell compartments, this can be a good place to store any extra shots.
This comes with a wide ejection port opening that will allow fast loading for your shotgun. Considering that you have this and the shell holder on top of that, the possibility of reloading your gun fast is more than likely.
Another great thing about this is that it is an easy to install, bolt-on kind of rail. So if you don't have any gunsmithing skills, you can breathe a sigh of relief. Just tack this on your Mossberg 500 and you should be good to go.
The good news is that this is compatible with most Mossbergs. So if you're looking to turn yours into a force of nature, then you might want to consider the AIM Sports M-Lok Modular Rail as a possible addition.
The AIM Sports rail is probably the best-designed rail for tactical purposes. It's definitely designed for situations where you would likely need additional shots on hand (like in a self-defense situation), because you may miss your shot and only have one shell on you. That could spell danger.
The fact that it allows you to hold up to six shells and has a very large ejection port opening to ensure fast loading is what makes this the best of the best among tactical offerings. If this is something that you consider to be your dream rail for a Mossberg 500, you'd be insane not to consider getting this.

Six extra shots ready to be quickly loaded is definitely a necessity in such a situation. Other than that, you’re looking at one of the best Picatinny options for a Mossberg 500 on the market. If you fancy yourself a fan of this kind of product, then you’re probably going to love the TacStar.
