Ok for first one - Tipton Best Gun Vise

Cheap plastic everywhere. Gun will move very easily, and really doesn't fit stock with pistol grip. Wants to roll around with rear stock grip. Have to constantly recheck alignment when mounting a scope because just handling the scope will cause it to roll in the vise and therefore be off level. Good for cleaning and mounting other things on weapon but for precision scope mounting get something else because this just doesn't cut it.
