Came across this on YouTube. I had a friend who had one back in the day (when firearms owners were trusted with such things, not like all you homicidal maniacs today, on the verge of snapping, so you can't be trusted with mags bigger than 5 rounds etc.
I think it was the late 80s, it was just a quirky non-restricted 9mm carbine back then, used a HK style roller locked bolt. Was fun to shoot and seemed very "space-aged". I recall it was very light. Very outside the box with helical 50 and 100 round mags. I remember the rear sight was attached to the mag, so sight adjustments were all done with the front post.
