Ruger Jmx-1 Rotary Magazine Fits American Rimfire 77/17 77/22 17 Hmr 22 Wmr

The Ruger 90076 JMX-1 9rd rotary magazine from Ruger offers a reliable, compact feeding solution for 17 HMR and 22 WMR shooters, combining a black plastic body with a steel feed for smooth, consistent chambering and long-term durability. Designed to fit Ruger 77/17, 77/22 and American Rimfire models, this rotary-style magazine holds nine rounds and keeps cartridges aligned for positive engagement in varmint hunts, small-game excursions, or precision plinking at the range. Its plastic construction reduces weight without sacrificing strength, while the rotary mechanism minimizes spring tension and enhances feed reliability compared with single-stack designs, making it easier to load and less prone to stacking issues during rapid-fire strings. The JMX-1's black finish blends on tactical or wood-stock rifles and its Ruger-brand compatibility ensures a drop-in fit for owners who want a dependable spare or replacement magazine that performs under field and range conditions.
