Simple, one-button takedown for quick and easy field-stripping and proper chamber-to-muzzle cleaning. Pressing a button in the back of the frame allows the barrel-receiver assembly to tilt up and off the grip frame without the use of tools.
Ruger® redesigned the platform of their famous 22 pistol to make the Mark IV™ 22/45™ LITE Semi-Auto Rimfire Pistol with a simple rear-mounted takedown button and a frame-mounted pivot pin that eliminate the complexities of field stripping previous models.
