Description
This 3D-printed magazine extender increases the capacity of our OOD Original Tachi and Koda magazines. Pop off your base plates and very firmly press-fit on until you hear the one-way detent hooks click. This accessory continues the follower channel and spring compression cavity, increasing capacity by reducing the maximum rate of fire.
* These adapters are Not recommended for Low RoF Tachi Mags since the follower spring is shorter.
