Excellent tool that addresses the problem nicely. Allows for a much easier barrel change by the end user.

If you’re using an AR-15 tool, you’re taking a risk. This thing is the money!

This wrench is very well made and the shipping was fast . Unfortunately this wrench got to me before the barrel i ordered from another supplier. So it sits on my bench while I wait 🤷♂️.
