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
