All forgered receivers are mostly the same anyways. There are some new forged receiver sets from the likes of companies like PWS and 2A Armament that offer unique forged designs.No big loss as far as I'm concerned. Anyone somewhat mechanically inclined can assemble an AR that will rival/surpass Colt's offerings. For less money.
My Poverty Pony is a good example, functions perfect and shoots great. No need to spend Colt prices.
I want to get 2A's lightweight Palouse set when they release it fornthe basis of a lightweight build. It costs half as much as their billet receivers and is the same lightweight.
