BigBill, I have the same 6X42 German reticle scope on my CETME. I like it, just put that pointed tip of the bottom post on target, and it's pretty accurate! Previously, I had it on my .223 Bushmaster Bullpup, but never could get the eye-relief quite right. It's perfect on the CETME. With the chopo's fairly light recoil, it should remain in good shape.
