I have the 93R17 BTVLSS. I just today removed the Thumb hole stock and installed a Boyd's Rimfire Hunter. I could never get a good picture in the scope with the thumb hole. With the rimfire hunter it is a night and day difference. When I bring up the gun it is amazing. There is no creeping and crawling on the stock to get to get a good view in the scope. Off to the range in the morning.
