Pencil head - NcSTAR Universal Pistol Rear Sight Tool

Easy to use and stout. Best to get two 1/4-inch x 1-inch long lag screws and washers and then attach to wood base (I used a 2x10 board remnant about 18-inches long). Mounting on wood base helped to stabilize tool while carefully torquing the new rear sight into the final position. Suggest that you mark where your old rear sight is located to help position your new rear sight. I used masking tape with black ink marks. Place tape on slide where it will not be scraped off during old sight removal then install new sight to align with your tape marks.

Overall, it is intuitive to use, but I wish I could have found instructions with my rear sight tool. There is a good YouTube issued by NcStar that you can watch on how to use it otherwise. It does come with a nice nylon storage case. Basically this tool should pay for itself with one use.
