Hk revival - Spuhr Stock Assembly for G3,MP5,HK33/53

I purchased the Spuhr stock to update my 1950s HKG3 designed rifle. It is a vast improvement to the original design, however, it renders the original rear sight unusable. It is perfect if you are using optics. It is better than the original G3 and HK collapsible stock. Easy to install, just need to use your original buffer assembly and back plate from any G3 stock assembly. I am very happy with this well designed stock.
