    This coupler is made for

    Posted by Lawrence M. on 17th Aug 2017

    This coupler is made for 20 or 30 round mags. Because I live in Colorado, the largest mag I can have is 15 rounds. The 15 rd. mag in the coupler will not function as the mag is too short to seat into my AR. I believe if I had 20 or 30 rd. mags. they would fit fine. The coupler needs to be about 1/2 inch shorter in length.
