AK Mag adapter for Tokyo Marui M870

thingiverse

Here's my design of the M870 AK Mag Adapter, found on Airsoft Heretics. It works very well, you'll only need 2 M4x10 Screws and 2 M4 Nuts to hold the 2 pieces in place. For the spring of the lever, I designed it with a spring I found at home, so you'll have to glue one in place. A small nail will do the job at holding the lever in place. Be prepared to do some filing on the sides of the upper part of the adapter, I designed it to be a very tight fit, and even larger to be sure it holds on place without any play. Have fun !
