It will work on light duty stuff, like retaining a stock & etc. The Offset under mine is a Must for me. But the barrel breeching & tough stuff, the Parrot vice will not handle it........ just not enough mass & slips around too easy. I use the Wilton for that, it has two lockdown screws & it is staying put.
And if I need something larger than that, I have a BIG vice in the garage & you won't move or stress it. I do my heating & bending & etc on it, as it is KeithProof......
