True test - GG&G 30mm to 1in Scope Ring Reducer

These are on a 10-40 scope on a a national match armalite m-4 with armalite one piece ring set. They adapt the rings well enough for the armalite to print like a typewriter at 300 yards given the right load. Another set of the right rings would cost $70 or $500 ish for a scope that wasn't as good. if you need it this will do.
Pros: Does the job
Cons: Getting them situated is a pain
