Is there any interest at all?

Don,t know anything about the tool (always got hard ones that needed an EZ out) But the Challis Bushings are super Just did one of my guns this weekend with them Brian also makes oversize bushings for the holes that get the threads ripped also sells a special self starting Tap so you don,t need to drill the hole for the oversize bushings
Sounds like a Super Karma to Me
