I just bought some scope rings. They are Vortex tactical rings, the cheapy ones, $19 a ring with the three torx head screws per side. I noticed that Badger Ordnance builds there scope rings in pairs and are serialized together, I noticed Vortex does the same thing with there top of the ling rings. How important is this? Will my cheaper rings put undue stress on my scope? It's mounted on a 7mm mag.
