I don’t know who made mine ( from Woodcrafts) but they are Chinese copies. They do
Ok with a offset feature. I have used them for prob 50 builds I guess. I build on 2 vices
almost all the time. The modified knockoff Woodcraft vice & a big Wilton vice. The knockoff
I have Teflon jaw inserts & leather over them. The big Wilton I have just leather over the jaws.
It’s worked well for me. I like to o do almost all my work with the barrel in the rifle too.
I want the lock in & barrel in & pinned ASAP.
I built over 50 rifles on a little red 4” craftsman vice & a 2x4 sticking out from the workbench holding the forestock up.
It doesn’t matter, it is what you get used to.
I think Jerry Crawford made the offset for me. It works well.
One might notice I have a piece of 2x4 or 2x6 under the front base of each vice. That is to get the vice out off the bench, so I can mount something long (as in a barrel) in a vertical position & not be restricted by the work bench top.
If I want to work on the buttplate area, I can tip the stock muzzle down in the green vice & have the muzzle sitting on the floor or a bucket, and have the buttplate just above waist level. If the vice is not offset on the bench, you can't clear the bench top & do this.
