This Magazine coupler for your Mini-30 5 round magazines. I use mine to prevent myself from loosing my second magazine while hunting. It also makes it easier to remove the magazine from the rifle because you have something to hold onto. Just remove the floor plates from your 5 round magazine and replace with this part.
It’s recommended you use some kind of a cover on the magazine not being used if you’ll be in the field for a while.
New for the second generation parts: The new parts are made to work with the locking floor plate retainers that come with the Ruger(5round) and ProMag(10round) magazines. There is now a hole in the back for disassembly. To disassemble, insert a hex key and use it to pry up on the floor plate retainer to slide the coupler off the magazine body. See video for an assembly demonstration.
This part is made to order using 3D printed Polyamide (SLS) and has an approximate 3 week lead time.
***Does not work with Ruger brand ten round magazines***
