I recently acquired a Ruger Precision Rimfire Rifle in 22LR. I'm pairing it with a Sniper ZT 5-25x50 FFP scope. I'm looking for a recommendation on the best rings for this application.
You might want to try the Burris signature rings. I only suggest these because that scope only has 50 MOA of adjustment and the rail on the RPR is 30 MOA. You might not be able to get a 50 yd zero. With the Burris rings if you run into trouble you can get the offset inserts to offset some of that 30 MOA.
