PMA Tools raw vise with 4 bolts is very strong and slip resistant.
https://www.pmatool.com/barrel-vises/I have only used mine on steel barrels, several on and off re-barrels. I use it to clamp steel barrels to remove stubborn brakes. I mostly use an action wrench in my bench vise for doing barrels, easy to back off nut and unless the barrel was installed dirty, they should spin off by hand quite easily. I have had barrels (Savage is all I do), where the threads were full of blasting media and grease and had to be turned off almost the entire way with a strap wrench.
New barrels, carbon and steel, with a bit of anti-seize will spin on by hand easily right up to your guages and allow you to feel the contact instantly. Its a simple job, Ive done many without an issue.
Im not calling it the best, Im just showing you an option that I have used fo several years without fail.
