Standard AR-15 vice blocks and other tools are dime a dozen and easy to find for almost any task.  Is there a recommended bench vice block to hold a .308 lower on a vice?  I know I can use the same setup if I want to hold it via the receiver extension, but is there a magazine block type of vice mount that is the go to for .308?
Plays well with self, and cleverly disguised as a responsible adult.

I'd try over here:

Also, I have one of these:

It has worked as advertised over 7-8 jobs, definitely worth the money spent.

This is the best one I've ever found, and it fits 15s and 10s!

I used a PlastixRevolution  upper receiver block for removal and retorquing the barrel nut on an Armalite upper receiver when installing a free float handguard. I didn't want to spend a lot on something I'll probably only use once.

I believe it has a 50ft/lb torque limit  by the manufacturer since it's made from plastic. It didn't flex or seem like it would fail when I torqued the nut to 50lbs. Likely it will survive a higher torque. They also make a receiver block for the lower that fits the mag well.

They're local to me so I contacted them and picked up a block the same day.
