Ruger 40149 Mark IV 22/45 Tactical 22 LR 4.40 10+1 Blued Black Checkered Polymer Threaded Barrel

Ruger's Mark IV features a simple, one-button takedown for quick and easy field-stripping and proper chamber to muzzle cleaning. The recessed button in the back of the frame allows the upper receiver to tilt up and off of the grip frame without the use of tools. Its internal cylindrical bolt construction ensures permanent sight to barrel alignment, while the contoured ejection port and easy-to-grasp bolt ears allow for durable and reliable operation. The accurate sighting system features a drilled and tapped receiver for Weaver- or Picatinny-style rail. The Mark IV is a single action and utilizes an ambidextrous manual safety, push-button magazine release located on the left side, and an ergonomic bolt stop. Included is a washer and two magazines. This 22/45 Tactical model features a 4.4" threaded barrel, polymer grip frame, black oxide metal finish, 1911 style black grip, fixed front sight with an adjustable rear, and top and bottom Picatinny rails.
