Airsoft AK to M4 handguard RIS rail adapter

thingiverse

I designed an adapter for my 8+ year old CYMA AK so it can fit a M4 style rail as there are so many available. This adapter only fits the Tokyo Marui style AK's such as CYMA, DBoys etc .. Does not fit VFC, LCT or E&L style. I have included the Fusion 360 file so it can be remixed as my skills on CAD are very basic. You will need an inner barrel about 240mm depending on how you mount the suppressor. There is no outer barrel as the suppressor is glued to the rail. The rail I used is here: https://www.thingiverse.com/thing:2253858/files I would recommend printing the rail at about 102-105% as it is a tight fit onto the adapter. Hopefully all the bottom holes line up - if not you could modify the Fusion 360 file. There is no holes for the hop up as I think it's better to mark the holes for your specific hop up unit and then drill holes. I also used an old M100 spring to push the hop up tight to the gearbox. There is also a small spring to push the dust cover back so it doesn't rattle. Any improvements would be good to hear! Made with my stock Ender 3 Pro.
