I have the Mark II BTV, love it, great trigger right out of the box. Put my cheap tasco 3x9-40mm on it and took it out, was really impressed with how accurate it was. I only shot a few groups at my targets, both sets of 4 shots ended up in the same bullet hole at about 25 yards. I also brought some targets hanging from a metal rod for the 22 semi. When we were done I started shooting at the metal rod (about 1/2" diameter) at that same distance , hit it 4 for 4.
Can't wait to take it out at a proper distance
