How to Reverse the Magazine Follower Button on a Ruger MKII

The Ruger Mark II is a .22LR semi-automatic pistol. It is the third variation of the Ruger Standard pistol designed by Bill Ruger. The design is based on a combination of the Japanese Nambu pistol and the German Luger. The Mark II M-10 magazine was designed to be adjustable, allowing it to fit in the Mark II, Mark I and Standard models. It has a 10-round capacity.

Instructions

    • 1

      Remove any ammo that may still be loaded in the magazine.

    • 2

      Hold the magazine upside down and insert the punch into the small hole in the base of the magazine block. The punch will depress the block-retaining plunger inside the magazine, allowing you to remove the block.

      Slide the block forward toward the front end of the magazine. The internal parts of the magazine are under spring pressure, so use care when removing the block. Once it is removed, set it aside.

      Slide the follower-button down until it is centered in the round opening at the bottom of the magazine. Pull it out.

    • 5

      Insert the follower-button into the round opening on the opposite side of the magazine; slide it back to the top of the magazine. Compress the spring and return the magazine block.
