is the best in class Classic Army B&T folding stock. It is a twin
to the HK model at more than $200. This stock comes with a mounting
pin and will fit right on your GSG 5 carbine. These are the best
folders available for your GSG - widely copied, but never equaled. Don't waste your time with lesser quality - this is
the one you're looking for. I offer a 100% money back guarantee.
