I would suggest a pattern makers vise instead. Called a carver's vise or guitar makers vise. Mounts way more sturdy than the real avid. Soft, rotating jaws. Holds everything I've got super secure. I use it to clean guns, mount scopes, mess with bedding actions, torque on muzzle stuff, all kinds of crap.
Thank's Stunt & John, Very good marketing from RA. I seem to be consistently disappointed with interweb purchases.I didn't think it would be much good for heavy tasks. I have a barrel vise & a regular 3" vise with magnet attached soft pads, as well as a Tipton's Best gun vise, which I don't really consider a vise as much as a gun holder. I am mainly trying to free up space on my bench. If the RA vise is a little better than the Tipton and if it can handle a few more tasks it will be a fair but expensive replacement. I have found my barrel vise very useful ( in addition to changing barrels) for light but important tasks like barrel cleaning & scope mounting etc but it (can't remember maker) is big with hard edges & wooden blocks & great for changing barrels. I have it set up to be easily installed & removed. The Tipton can also be moved off my bench to my desk to be used as a gun holder.
Same as comment above re barrel swap or high torque applications. It is a very well made vise, smooth turning, but I wouldn't apply too much force on it. I don't barrel swap so I won't say it cannot do it.
