For context I’m using: https://www.thingiverse.com/thing:5187279/files

I could only put the barrel in via the outside as it won’t fit from going in via the inside of the upper. When I attempt to attach the barrel retainer and tighten it down via the 4 bolts it pushes the barrel in too far and then the bolt won’t seat correctly. Has anyone had this issue or am I just doing it incorrectly?

The upper in the file is supposed to be adapted for Glock barrels
