how do you hold a barrel to remove an a2 screw on flash suppressor ? thanks in advance
That'd have to be an extremely brittle, low-quality barrel if you can twist it from taking off/putting on a muzzle device. They're not torqued a whole lot (If I recall, under 50ft lbs).They sell actual barrel vices that clamp on to it. Without a vice, you're likely to twist the barrel itself.
I don't think they adjust small enough to clamp on a bare barrel.....They use the strap wrenches a lot to install free float tubes,I guess if you wrap the barrel with enough leather to take up the slack it would work,but he is trying to hold the barrel to remove the comp,not remove the barrel itself...
Negative on the vise blocks.....That is how you twist a barrel......If you clamp it right behind the comp and remove it,it is much more rigid and will eliminate the twist threat....I've got a small strap wrench that would definitely work on a barrel. Had it for years, not sure of brand or where I got it. I would also recommend using an upper vice block and just this as additional support.
I would be all for using a pair of those in tandem.....One on the barrel right behind the comp,the other on the comp itself.....That should break it free quite easily I would imagine..
