Been working slowly on a budget GK using parts from an awesome pep file by Uhu02 (particularly the supressor as I can't get one into Canada). I've turned my attention to the scope, but in the pep I have the thing is only about .75" diameter. I was under the impression that the Compac was actually more like 1" external diameter, and was thinking of scratching the scope the same way I did my M38 (some ABS and a chopped-up funnel) as no one seems to be offering resin pieces at the moment. The reference pics I have are however a little difficult to scale accurately and don't line up nicely with my mauser dimensions. Knobs and other greebles on top I can work out later, but does anyone happen to know what the overall dimensions for the various parts of the Compac tube-eyepiece are? Cheers!!!
