Looking to buy a rifle cradle/gun vise for cleaning, scope mounting, bedding etc. Looking at the MTM Portable Rifle-Shotgun Gun Maintenance Center ($45) the basic Tipton gun vise ($45) or the Tipton best gun vise ($100). These are just a few I saw out there, unfortunately I don't have the room to build my own right now. I was wondering folks opinion on these or another alternative, thanks for any and all responses.
