I bought this rifle used right before the panic buying started. I got a good deal I think on it and now I am thinking about selling it. With all the panic buying I can't tell what these things should be bringing. What would be a good price for the rifle? It has a 20 inch barrel, A2 Stock, and black bolt carrier group. The best group I have shot with it is just over 1/2 inch at 100 yards.
