What non printed parts do I need to complete this build I know I need a cmmg 22 lr conversion BCG and protobarrol but is the max upper required for this build ??

Assuming your talking about the DB9-22, a project I’m working through myself at the moment, the upper is comprised of all printed parts except for the ones you’ve already noted.
Thank you and yes it’s the DB9-22
Also, you’ll need the FCG reinforcement plates. I couldn’t find any STLs for them as these being 22lr, we don’t need titanium or stainless, so printed ones are fine. I had to convert the DXG files to a sketch in Solidworks and create the STL from that.
