Does Ruger sell scope mount bases for Ruger .22 pistols?
Ruger produces four scope bases to fit the Ruger Mark I, Mark II, Mark III and .22/45 pistols. The standard Ruger base, part number A07000, is 3.421″ long, the distance between the rings is 1.888″. The extended base, part number A07001, is 4.125″ long, the distance between the rings is 2.625″. These bases will only accept Ruger scope rings. We also supply a black ‘Weaver-Style’ base, part number A07052B, and a gray base, part number A07052G, both will only accept Weaver Rings. Scope bases may be purchased at ShopRuger.com. These bases require the pistol to be drilled and tapped. However, we do not offer drilling and tapping as a service.
