These rings are arguably the best on the market. Supplied with decent instructions & a wrench, they install quickly & easily and your scope is solidly mounted.
Probably the best testimony of these is this: You can take a new scope, put it in these rings, take the scope off six months later & find no ring marks. The scope is as new - unless you damaged it in other ways.
In this day & age of things being built to be disposable, it is nice to have a product so consistent in quality as these rings are. Whether they are on sale or not, you will never regret using these rings.
Pros: Precision manufacture, no scope damage
Cons: None
