Here's my little project I've been designing for about a year now. CAD design is near complete so machining will start very soon. Everything except the scope has been designed one off. 509mm inner barrel length in a 30" overall length. Custom hop up design using vsr buckings and barrels. Open to thoughts and criticism!!

I'm confused by the hopup-cylinder head interface. In the VSR system, the nozzle is supposed to go in the bucking, but this appears to be sealing against the outside. Am I looking incorrectly?

As I thought. Your nozzle doesn't go into the bucking the way a normal vsr nozzle goes into a vsr bucking. Instead you made a hopsystem who's nozzle-bucking interface is more akin to an aeg system. I think this will result in the the bb being placed too far back resulting in major inconsistency.

Any reason in particular you're making your own scope rings rather than buying a set? Function? Or just aesthetics?
