I have been looking at some different rem 700 short actions for a 20BR build i am thinking of doing. Anyway while looking at a few different rem 700 actions i saw something that i dont ever recall noticing before. The rifle was a 222rem. the receiver was shaped a bit different were the back (closest to the butt stock) scope mount goes. It looks like the receiver is cut out a bit. Actually its cut square quite a bit, and the scope mount area looks more flat. All my rem 700 actions are one solid piece of metal in this area, and more rounded. I hope i am explaining this properly. whats the idea behind the cut out square area under or in front of the back scope mounting area? Lee
