Sure.T mag coupler

thingiverse

coupler to join two sure.T mags end to end so you can rain double the hell fire! Caution, when plugging them onto the mags you may not be able to remove them. The print layers seem to grab pretty good. Two versions. One with the darts facing the same direction (pictured) and one where the darts face opposite directions. If you use this, make sure that you have good spring tension for the mag holding latch. The extra weight can cause the mag to fall out and damage the bottom mag. Ask me how I know this. :-)
