Most anything good can be bought from Brownell's.
Much depends on how tight the barrel is.
Some of the bench top barrel vises will work, but for tight barrels you really need a professional set up, which usually is a hydraulic jack type barrel vise using fitted inserts.
My buddy uses Kelby Panda actions and Bartline barrels, all high dollar. He has a barrel clamp type that he can put on his truck bumper and change barrels right there on the line.
Last I heard he had Bartline barrels in 6.5, .308, and .223, and a Kelby .223 size bolt, all of which interchange perfectly.
Precision has gotten to the point that he can buy a Bartline barrel and just screw it into a Kelby action and head space is perfect with no headspacing or fitting at all.
He has his barrels nitride treated and at last count, his barrel life was greatly extended.
He bought a special action wrench for the Kelby receivers.
For standard actions, like Remington, most people seem to use receiver wrenches and fitted inserts that wrap around the front of the receiver.
There is a type that fits inside the receiver that grips the locking lug recesses, but I haven't heard a lot of reports on this type as to how they work.
The key is getting a barrel vise on a FIRM bench that won't allow flexing or moving. Any movement and the springing can cause problems.
Some of the barrel clamp type barrel vises can't grip tight enough that a tight barrel will just turn in the vise. That will often strip off any bluing or finish.
