Rimfire black matte rv4 rifle scope - Weaver Rimfire 4x28mm RV4 Duplex Reticle Rifle Scope

I purchased two of these to replace 3-9 power scopes by other manufacturers. One was placed on an old Remington Nylon 66, the first of the synthetic stocked rifles circa 1974. The second was placed on a recently purchased Ruger 10/22 with a black synthetic stock and a secondary market receiver that had a forged Picatinny rail included. Both were mounted using Weaver 6 bolt one inch scope rings with integral mounts. Both locked up snug and tight and after a few hundred rounds are punching one inch holes at 50 yards with 15 rounds of Eley Prime Target .22 cal. Goof price for the product.
