his set is for lest say old school paintball markers. that will usually use a clamping elbow to attach a hopper to it. with this model can you directly attach the magfed adapter. for a cleaner look
this model works great it with both the 7round, 12 round and Zeta mag.
to finish the clamping part use a m3 bolt that is 16mm in length and m3 nut
installation: you need 1 spring and 2 pins
Link to the TIPX installation video
UPDATE: I have added some other ID sizes. and updated the angle of M3 it was a bit off this one should be better
