I'd say excellent deal. I have a compact Pentax I gave $80 for, and thought it was a great price. Just finished setting up 3 scopes for mounting it to the scope. I used : 1) weaver accessorie ring
2) weaver to weaver riser, ( no slots, clamps on top and bottom. )
3) epoxied a 5 slot mini rail to the range finder.
The mini rail gets clamped the riser, the riser gets clamped to the accessorie ring. One thumb screw releases the riser from the ring and can be put on another scope. It is mounted so eye relief is almost the same as the scope. Works great for quick ranging. I'll post some pictures when I get home. Bill and Addi
