Great purchase as an add-on to Leupold scope/rings purchase. After spending a fair amount of money on a very nice Leupold scope with PRW rings, it seemed like a good idea to spend a little more and get something I KNEW would enable me to properly mount everything up. It was comforting to know that the driver matched up perfectly with the screws and I didn't have to worry about it stripping the screws or it slipping out and damaging the rings, the scope or the gun. A small price to pay for a good bit of peace of mind.
Pros: Magnetized tip
