This review covers the Lucky 13 "Unimag" 25-round magazine for Ruger American and 77/22 platforms in .22 Magnum and .17 HMR. The magazine is constructed from 6061 aluminum, features a high-viz anti-tilt follower, and is made in Australia. While the 25-round capacity is restricted in some Australian states, a 15-round version is available. The review includes a detailed disassembly and reassembly guide, a comparison with a Volquartsen magazine, and a live-fire test with various ammunition types, noting minor feeding issues that improved with use.
