Ruger Mkiii Mkiv & 22/45 Pic Base

The Ruger Mark III, Mark IV & 22/45 Pic Base is a genuine Ruger factory accessory engineered to modernize the ergonomic and optic-mounting capability of three of the most popular rimfire pistol platforms in law enforcement training and civilian marksmanship. This 1913 Picatinny rail adapter transforms firearms with factory pre-drilled receivers, allowing shooters to mount contemporary optics, lights, and laser systems that were impossible on original configurations. Built for operators who demand reliability in training environments, duty qualification courses, and precision shooting disciplines.

Constructed to Mil-Spec 1913 Picatinny profile standards, this rail provides a solid mechanical interface with zero tolerance for shift or creep—critical in firearms used for transition drills and low-light training. The compact profile (7.45 inches overall, 0.13 lbs) maintains the inherent balance of Mark-series pistols while adding forward-mounted capability without inducing muzzle-heavy characteristics. Installation uses three precision screws supplied in the kit, engineered to engage factory pre-drilled threaded holes with no modification to the receiver required. The aluminum construction resists corrosion and maintains dimensional stability across temperature and humidity extremes encountered in field environments.

Law enforcement academies, competitive shooters, and military combat pistol instructors have long relied on Mark-pattern rimfire platforms for cost-effective, low-recoil training alternatives. This rail directly addresses the limitation of factory-fixed sights by enabling red-dot optics, thermal imaging, and night-vision-compatible accessories. Compatible exclusively with Mark III, Mark IV, and 22/45 models featuring factory pre-drilled receivers—Mark I and Mark II platforms are not supported. Field installation requires no gunsmithing; the three-point fastening system ensures secure mounting for thousands of rounds without re-torquing or maintenance downtime.
