M&P 15-22 Magazine Coupler
thingiverse
Coupler for Swith&Wesson M&P 15-22 magazines. The holes are 1.75mm and are sized for M3 bolts. To connect the two half's it's best to either use bolts and nuts, or if you have them available, threaded inserts. The photos (sorry for the potato quality) are using threaded inserts I purchased from here: https://www.ebay.co.uk/itm/262993790868 ** UPDATE 15/11/2017 ** Added a slimmed down version with a curved inner contour and longer middle connection. Reduces bending when heavily tightened and allows it to fit other magazine types reasonably well. ** UPDATE 02/01/2018 ** Added a baseplate replacement for the coupled magazines, holds them more securely in place.
