Mark II .22 Long Rifle - 10 round Mec-Gar magazine with a blued finish MGMK22LRB. The magazines don't work in the Ruger Mark II 22/45. May not feed reliably with a Pac-Lite barrel. These magazines are also compatible in the late model Mark I (1971 and later manufacture). They are stamped A-100 on the frame under the left grip panel. To use the magazines in the earlier Mark I the follower button has to be switched from the left to the right side of the magazine.
Constructed from certified carbon steel and features a heat treated housing and high-impact polymer or certified carbon steel follower and floorplate. The magazine spring is made of high strength type "D" music wire-the strongest wire available. TIG welding provides additional strength and a seamless finish. Each magazine surface is specially treated to ensure high corrosion resistance.
