Ruger BX-15 15-Rd Magazine for American Rimfire/77 17 HMR/22WMR - Black (Model 90585)

The Ruger BX-15 is a 15-round magazine purpose-built for Ruger rimfire rifles chambered in .17 HMR and .22 WMR. If you own a Ruger American Rimfire or similar Ruger rifle in these magnum rimfire calibers and you're tired of frequent reloads at the range or in the field, this extended-capacity magazine delivers the same reliability and durability that rimfire shooters have come to expect from Ruger's magazine line. The BX-15 lets you spend more time shooting and less time managing magazines.

Built with practical, field-proven engineering, the BX-15 uses proven feed-lip geometry and pairs it with an anti-tilt follower that keeps rounds feeding smoothly and reliably. The stainless-steel feed lips resist wear and corrosion, while the glass-filled nylon magazine body is light, durable, and built to withstand the demands of regular shooting. Whether you're zeroing at the range, running drills, or hunting small game, the extra rounds mean fewer interruptions to your shooting rhythm.

The black finish is subdued and practical—no flash, just a straightforward magazine that fits your rifle and does its job. If you've already standardized on Ruger rimfires in .17 HMR or .22 WMR, adding one or more BX-15 magazines is a simple way to increase your trigger time between reloads.
