AK Mag adapter for Tokyo Marui M870

thingiverse

Here's my design of the M870 AK Mag Adapter. It works really well and only requires 2 M4x10 Screws and 2 M4 Nuts to hold the two pieces together securely. The spring I used for the lever is one I found at home, so you'll need to glue it in place. A small nail will do the job of holding the lever in position. Be prepared to file down the sides of the upper part of the adapter as I designed it to be a very tight fit. You may even need to make it a bit larger to ensure it holds securely without any play. Have fun building!
