The Ruger BX-15 Magnum steps up your rimfire game by delivering extended capacity without the bulk. This factory magazine feeds 15 rounds of .17 HMR or .22 WMR, giving you significantly more range time between reloads while keeping things compact enough not to feel awkward in the field or at the bench.
Ruger engineered this magazine using the same proven feed lip geometry that made the .22 LR BX-15 and BX-25 magazines reliable workhorses across the rimfire community. The stainless steel feed lips won't wear or corrode, and the constant-force spring maintains consistent tension on the follower through the magazine's full capacity. That means smooth feeding whether you're down to the last round or running a fresh mag at the start of your session.
The magazine body is made from glass-filled nylon that resists impact and handles rough conditions without breaking or cracking. The high-lubricity polyacetal anti-tilt follower keeps rounds aligned and feeding straight into the action. Everything comes apart easily for cleaning with just two stainless steel screws, so maintenance is no hassle. This entire magazine is manufactured in the USA, backed by the quality control you'd expect from a Ruger factory product.
Fits Ruger 77/17, Ruger 77/22, Ruger American Rimfire, and Ruger Precision Rimfire rifles chambered in .17 HMR or .22 WMR. Whether you're a target shooter working through a box of ammo or a varmint hunter looking to reduce downtime in the field, the BX-15 Magnum gives you more rounds between mag changes without sacrificing the handling and balance your rifle was designed for.
Yes, the BX-15 Magnum is designed to work with Ruger 77/17 and 77/22 rifles chambered in .17 HMR and .22 WMR. It's also compatible with Ruger American Rimfire and Ruger Precision Rimfire models in those same calibers. Some older rifles may need minimal fitting, but the magazine is engineered to match Ruger's factory specifications.
The standard magazines that ship with most Ruger rimfire rifles are 9-round rotary designs that sit flush against the rifle. The BX-15 Magnum holds 15 rounds in a detachable box magazine, giving you fifty percent more capacity. While it extends below the receiver, it provides a handhold for easier loading and reloading between shooting strings, which many users prefer for extended range sessions.
Very much so. The magazine comes apart completely by removing just two stainless steel screws, making it straightforward to clean all components. The durable polymer and stainless steel parts won't rust or corrode, and the design allows for thorough inspection and maintenance without special tools or procedures.
Ruger's factory magazines are manufactured to the same tolerances and quality standards as the firearms themselves. The BX-15 Magnum uses proven feed lip geometry from Ruger's successful .22 LR magazine lineup, combined with quality components like stainless steel springs and anti-tilt followers. Field reports from users consistently show reliable feeding across various ammunition types and shooting conditions.
