this nut driver is a nice addition to my gun tool box.....makes installing the Challis bushing a snap!!

I like how the bushing fits flat in this tool which makes it easier to get the bushings in to the frame. The tool company that they picked is also great. I have been using the 3/16x60mm Wiha Precision Nut Driver for years now in my shop to install Glock front sights. This simple tool will last years.

Highly recommend. Right tool makes all the difference.

Hi-quality German-made tool by Wiha, yet not expensive ($12). Installing or removing Challis hex-head grip bushings is easy with this tool.

This tool is nice quality, made in Germany. Excellent value.
