I’m looking to swap the barrel on my howa mini. I’ve scoured the internet and can’t seem to find a solution for an action wrench. I found some good info on a brownells wrench recommended using flat bottom and m70 top but the wrenches have been out of stock for some time and I’m tired of waiting. I found an internal wrench (can’t remember where) but I was concerned with using an internal wrench for factory barrel removal. Also I’d rather not relief cut the factory barrel as I’d like to be able to reuse it as needed. Anyone have any experience with these things or any suggestions
