I just ordered a new Aimpoint T-1 Micro scope and it is great. I got the GG&G mount that has the built in lens covers, which Aimpoint somehow forgot to put on the scope.
I have it mounted on a Bushmaster lightweight barrel. The setup doesn't weight much more than a M-1 Carbine with a whole lot more firepower.
These scopes are cool beans. I may have to buy another one.
