​AR15 - AK/AKM - AR10

MAG|Coupler™ Magazine Couplers maintains the utility, function, and round-count of each magazine while keeping two magazines paired for storage and handling. The MAG|Coupler™ replaces the magazine floorplate to join two like magazines back-to-back. It does not alter magazine capacity or firearm operation.

"The MAG|Coupler works great!  I took it out to the range yesterday and cycled 100 rounds through with no problems."   Mike, Yorba Linda, CA
