Though most G/K43s are equipped with a telescopic sight mounting rail, the vast majority of the rifles were issued in their standard infantry form without a scope. When equipped with a scope, it was exclusively the ZF 4 4-power telescopic sight.  No other known scope/mount combinations were installed by the German military on G/K43's during World War II. Many strange variations have shown up after the war, but all have been proven to be the work of amateur gunsmiths. Rifles with broken-off butts are common, as German soldiers were instructed to render semi-automatic rifles useless when in danger of capture.
Simple and sturdy, this pack is very quaint. The entirety of the construction of the bag seems to be pretty darned tough, the East Germans not playing around in making military equipment. The back straps may seem primitive, but they are indeed sturdy. They are, of course, Y straps and double as suspenders for a waist belt.
The bag I got was bigger than expected, and what appears to be the picture of the product on this site is actually the bag when folded up. It can accommodate WAY more than a hefty lunch, and I intend on using mine for school.
Overall, I highly recommend this bag to anyone wishing for a cheap alternative for any more expensive hiking or school bag. It has a surplus smell, but this does nothing to hinder the product's functionality.
I thank this site for having such an awesome product at such a low price. You guys are crazy for having such brilliant deals. c:
