I recommend checking the NRA rules regarding certain Rifle Competitions and legal equipment to use. From what information I could find the Sightron SIII SS 10-50x60 Side Focus Long Range Rifle Scope could be used for F Class .22 Caliber Benchrest Competitions. However, I am unaware of what the most popular scope for that type of competition is.
Thank you for your inquiry. Yes, this scope is used in benchrest 22 caliber matches.
