I'm toying with the idea of swapping the stock out of my Crosman F4. As I search the internet, it seems that no one makes an aftermarket stock for any of the hundreds of thousands of Crosman/Benjamin air rifles that have been sold. It looks like the Remington (Crosman) Summit stock is a good fit (and a decent looking stock I might add) but availability of the stock seems rare. Does anyone know of any other options for this or am I just stuck with what I have?
