Longrange military - Burris Airgun / Rimfire Signature 1 inch Rifle Scope Mount Rings for .22 grooved receivers

Rings work great. Allow scope offset to adjust for extended range. I installed on a Swiss K-31 rifle with a clamp on mount and a vintage Weaver K4 scope. Use this combo to compete in vintage military matches at ranges from 100 to 1000 yards. The ring give enough elevation adjustment to adjust foe zero at 100 yards and adjust up to 1000 yards. The rings have stayed tight and secure and have worked great. Ordered with extra insert kit to enable 20 minute offset.
