Begadi/5ku B11 Spacer for E&L AKSU

As a Airsoft club we got us some E&L AKsu's and ordert for them B11 Rail mounts made by Begadi/5ku… the problem is that there is a 4mm gab between the Body and the B11 so I made a Spacer to fil the gap... what we saw was that each replica is different in tolerances in the body there for you might have to add or remove materiel from the part that goes in the body…

I have Printed it in Sunlu PLA but havend had the chance to test it in the feeld jet
