Very durable rings - Weaver Cross Lock Rings

These are great mounts... solid, durable, steel. They are a bit heavy being steel, but they're not going anywhere once mounted. The only reason I didn't give them an overall rating of 5 was because the finish (silver) didn't match the finish of the base I had.
Pros: heavy-duty
Cons: weight is a bit of an issue
