Most Helpful Positive Review Polymer Magazine Coupler
I used these magazine couplers for metal magazines for my Ruger X 3 and they worked great. Took a moment to figure out how to assemble them but once I did its awesome. Makes it very easy to exchange an empty magazine for a full magazine.
Most Helpful Negative Review Works ok for ar/m4 style mags
Works great for ar15 style magazines because of the lip. With a little effort and cursing the couplet works as it should. However it does not fit 308 or ak style mags. However a must have if you have a ar15 style rifle

Great Coupler

by Dave, Verified Owner from CT, United States Written on July 3, 2024
Recently purchased two of these couplers, and I gotta say they work extremely well on USGI and standard AKM magazines. Couldn't get these on magpul magazines, which is a shame, but they did the job for me, especially at a low price. Highly recommend.
Pros:
  • Fits standard metal USGI and AKM Magazines
Cons:
  • Doesn't fit on all magazine brands, unfortunately
Best Used for:
  • USGI & AKM (Metal) magazines
Would recommend: Yes

Magazine coupler

by Tim, Verified Owner from MN, United States Written on November 11, 2023
Coupler works relatively well. I used it on metal 30 rd magazines from both Duramag & ASC. It works, but it is a very tight fit and hard to get on.
I only used 1 of the couplers on a pair.....concerned that as tight as they are, they might deform the magazines if I placed them higher on the body. Will see how they perform under actual shooting use.
Pros:
  • well constructed - seem to be strong
Cons:
  • very tight
Would recommend: Yes
