A pair of 30mm Vortex rings. I bought these 2 weeks ago, then promptly lost the receipt. It’s not worth the trip back up Island to try and exchange them. These are for Picatinny rails. Will fit 1913 rails as well. They’re flat black, not glossy blue, so they’ll be perfect for your little Ruger, or your pimped-out Airsoft build. These were never mounted or torqued down. Just taken out of the package, checked against my scope, then put straight back in the package. I can mail them. Depending how close you are to a gun shop, you might save a few bucks. These retail for $39.99 at Cabelas. Thanks for looking!
