The Ruger BX-1 10-round magazine is the standard factory mag for shooters running Ruger's rimfire lineup—10/22, SR-22, American Rimfire, and Charger platforms. If you're serious about .22 LR shooting, whether you're plinking, training, or hunting small game, having reliable mags on hand is non-negotiable. The BX-1's rotary design feeds rounds smoothly and consistently, and its polymer body keeps weight minimal while the steel feed lips handle repeated loading cycles without wear.
Built to Ruger's own specs, this magazine pairs the durability you need with the straightforward reliability rimfire shooters expect. The black polymer construction resists UV damage and won't snag on gear, and the rotary feed system is proven across thousands of rounds in the field and at the range. Ten rounds gives you solid capacity for most shooting scenarios without excessive bulk.
Whether you're stocking up for a dedicated .22 rifle or keeping spares for your Charger takedown, the BX-1 is the sensible choice—it's the gun's native magazine, made by the same folks who engineered the firearm itself.
