What is a Magazine Coupler and What Are They Used For?
A magazine coupler is used to fit two AR-15 magazines together. This is designed to help you reload your AR-15 rifle with a lot more speed and efficiency. Plus, it will allow you to keep some extra ammo handy at all times regardless of what your application might be.

Magpul - AR-15 / M16 PMag Link Magazine Coupler
Whether you’re hunting, target practicing or using your AR-15 for competitive shooting purposes, a good magazine coupler is a convenience when you want to save yourself time rather than waste it by manually loading one magazine.
What Makes a Great Magazine Coupler?
The most important question asked is: what distinguishes a great magazine coupler from one that is considered low-quality and ineffective? This list below will answer that question in a few parts. This is something to refer to when you’re a first-time user of these magazine couplers. You’ll never have to worry about having to buy something that is disappointing and cheap. With that said, here’s what distinguishes a good coupler from a bad one:
Material
Of course, the material is one of the most important aspects of any accessory. That’s because high-quality materials like polymer are designed to be tough and withstand all kinds of damage. The higher the material quality, the better it will last. Especially for years or even decades to come.
Installation
These magazine couplers are easy to install. This means you won’t have to rely on the services of a professional gunsmith to get the job done for you. Also, you won’t have to worry about the skill level that you have when it comes to gunsmithing skills. Luckily, all of these magazine couplers are all drop-in or easy to install.
Functionality
A great magazine coupler will allow you to be able to release magazines as quick and simple as possible. They will fasten and stay in place until you need them. While they are fastened, they will remain in place when you’re running or firing multiple rounds. So long as the screws or fasteners are tightened properly, you won’t have to worry about losing your extra magazines.

Pros and Cons of Magazine Couplers
Yes, you will get to experience the advantages of having a magazine coupler. However, there will be some downsides. This is what you might expect from a magazine coupler should you choose to get one for yourself:
PROS
Below are the main pros:
Faster Loading/Reloading
As mentioned before, these couplers are designed to keep your extra magazines handy until you need them. Since they’re closer to you, the unloading and reloading will be almost instant. This will definitely serve you well in the long run in pretty much any application. Especially if you’re in a target shooting or home defense situation.
Great In Case Of An Emergency
What if one of your magazines jam on you? Yes, it does happen to the best of us. It’s even more of a relief when you have two extra magazines handy just in case one fails. Not only are couplers great for faster reloading, but they’re also your “break glass in case of emergency” kind of accessories for your AR-15 rifle.
Hands-Free Magazine Compartments
Sometimes, holding an extra magazine in your hand will prove to be difficult. Especially when you’re trying to use your AR-15 with both hands. Your pockets won’t do you any good since the magazines themselves may snag inside them or on any parts of your clothing. You can consider this one of the many hands-free godsends that you can add onto your rifle at a moments notice.
CONS
Below are the main cons:
May Add On Extra Weight
Sometimes, if you’re carrying multiple rounds this will happen. Especially if you’re carrying more than two magazines at a time. The rifle may become slightly heavier than normal, and it might make it a little more uncomfortable to carry around. If you’re a first-time user, it is important to carry no more than two additional magazines at a time.
May Not Always Be Universal
Some magazine couplers will handle any caliber magazines. Some will not. This is where you’ll need to know what your AR-15 rifle is chambered in. If you fire 5.56 NATO rounds, then find a coupler that is compatible with those magazines. If you’re firing .300 Blackouts, find one that might be close enough to handle those kinds of mags. Universal mag couplers are out there, but they’re usually hard to find.
Conclusion
If you’re looking for the best AR-15 magazine coupler, you’ll know exactly what to look for. If not, think about what you might look for in an accessory that has the ability to hold extra magazines and allows you to reload your rifle in the shortest amount of time possible.
Once you’ve got a good idea, look through the list above again to see if they fit your criteria. There is nothing more convenient or reliable like a magazine coupler that will have all your extra shots handy when you need them the most.
