I have a G33/40 that has been sporterized somewhat just by putting a sporterized stock on it. It has not been drilled or cut. Is there a mount available to scope this rifle without having to drill the reciever because I know it will decrease the value of it and ruin the chances of ever restoring it. I also have a 1903A3 restored that I would like to scope but would prefer not to drill it. Is there such a mount available.
