Is it made of aluminum chain links, like a k98 or a G3 pull-through?My go to cleaning kit was made in East Germany for their AK 47.
I can use the pull through easier than the rods, faster too as I don't have to screw it together.
I just have to be careful not to drag it over the muzzle. Easy enough as I will wrap a cloth around the nuzzle and let it take the rub.
Those are cool old boxes.
