I got my first Mark II. Stainless 5.5 bull barrel today at a gun show. Looked a little rough, but it all came out with a little polishing. Came with a B-square no tap, scope mount, and a tasco red dot. Paid a little too much for it, but it was about the only thing that really caught my eye, that I wanted to have. Gave 425 out the door. But it's in about 90%-95%. Is the b-square mount worth anything. I probably won't use the red dot, as I prefer iron sights on a pistol. All I can say is that this thing will probably replace my MK III Hunter as a new range favorite.
