Use the FSB as a barrel vice?
Can I cause severe damage to my barrel if I place the front site block in the vice(think upper only, flipped upside down and FSB being clamped by vice) to install a muzzle attachment?
Barrel is a Colt 6920 with full FSB and the muzzle attachment is a Battle Comp 1.0; I'll need to remove the A2 first and that where I'm having the trouble currently. Normally I've been able to simply hold the barrel in one hand and wrench off A2s but this one won't budge.
I just don't want to wait for Brownells to deliver a barrel vise to do this, I'd like to have it done for this weekend.
