Most Helpful Positive Review Fancy little coupler.
These magazine couplers are about as necessary as any couplers out there. There's really nothing any of them will do that your favorite brand of tape won't do. That being said, these particular couplers by Mako Defense add a bit more flair to your setup than a roll of masking tape ever will. They also set the magazines at a stagger perfectly clear of the ejection port without creating a long mess of a magazine. Setup may be a little more difficult for the less mechanically inclined since instructions are not included (in my package at least). The locking tab at the bottom must be pushed ...

FAB Defense Modular AR15 Magazine Couplers

by Brian, Verified Owner from WV, United States Written on October 13, 2025
Metal magazines installed with no issues. Just push the latch tab into the grove in the magazine and they stay in place just fine.
Optics planet had an excellent sale price, their shipping is excellent, as usual.

It works as designed

If you’re running the old school metal magazines, these couplers work perfectly. Great fitment. No issues. Already have a second set on order.

Nice option

by Matthew, Verified Owner from FL, United States Written on June 5, 2024
This item is built well, it is sturdy and holds the magazines securely even from the bottom where it uses a small tab that slides under the magazine baseplate to keep them from slipping straight out. This coupler is a bit bulkier than the "normal" options but it doesn't add the clamping stress to your magazines either and if your not careful you can overtighten the screws and cause stress fractures on your polymer magazines possibly breaking them over the course of time. That won't happen with this coupler. I've only had this coupler a little more than a week and time will tell how durable it is but I believe FAB's coupler can have a place in your gearbag and at $14.00 it is worth it to me to find out. It is always nice to have more tools in your toolbox. Recommened.

Great coupler!

by Corey, Verified Owner from VA, United States Written on December 4, 2021
To start, I used this mag couple for a rifle other than originally intended; I used it for Galil mags. That said, it works great! The Galil mags were a bit tight and they do not engage the locking tab due to the way they are shaped, but because they are snug they do not slip out. The offset they provide is far nicer than simply taping your magazines together!
Pros:
  • convenient
  • Snug
Cons:
  • None
Best Used for:
  • Mil-spec M16 magazines
