I just sent back a cabalas gun vise the premiere vise as it would not hold my 308 cal rifles secure enough to use them at the range to sight in my scope on these rifles. Would anyone please recommend a gun vise/rest that is stable enough and built well enough to put a ptr-91, cetme, and also FAL 308 into it and fire the rifle to be able to check adjust my zero on the scopes of these rifles. I am will to spend up to $200 on the gun vise. please tell my also what company carries the vise/rests. i would prefer metal as opposed to plastic.
