Are you questioning my patriotism? ;^)
Never!!!!!!! (grin)
I remembered the M-14 from my time in submarines (we had a couple on board) and thought thet it looked a little familiar. My Dad was Army (jumped out of perfectly working aircraft!) and thought (but not sure)that it might be the M-21.
BTW, I spend summers in Montana---a VERY selection of weapons to be had thereabouts. Got some deer hunting in and had a lot of fun. I need someone to help me with the kill, but get a lot of leeway from the game wardens
