Barrel Vises vs Action wrench

[barrel-nut]

If your gonna get one or the other, get the Action Wrench.

JMHO.....:-))

+2. But if you can afford to, get both. I've done swaps both with, and without using the barrel vise, and I like it better with the barrel vise. Gives a little extra measure of control when setting the headspace and tightening the nut. It stops the barrel from spinning with the nut when you really tighten it down.
