Scored it at the weekend. Made in September of 1973, the Mohawk Brown version and doesn't look like it has done much work. Came with a 2.5X Bushnell Banner with the post reticle. USD80.00 all up! Didn't need it but they are rather unique and what a deal. Saw a Youtube video on how to strip it so got that covered. Anything else I need to know about it? Do they tend to cycle standard velocity ammo?
