    Awesome tool!

    Posted by Scott Young on Aug 26th 2019

    This is exactly what I was looking for. My multi tool slips and damages the castle nut but this tool fits perfectly without slipping and damaging the nut. It also doesn’t cost as much as a lot of the highly recommended other tools. Perfect for the DIY person that only plans on doing a couple guns.

    Saint Edge / Saint Victor

    This is exactly what I needed to remove the barrel nut from my Saint Edge and Saint Victor rifles! It’s super high quality and a perfect fit, plus it also works on your castle nut as well! Thanks BCM!
