Description
The BX-1-5 is a factory Ruger rotary magazine purpose-built for the 10/22 and compatible rimfire platforms. It delivers the same reliable rotary design Ruger's known for but in a 5-round capacity, making it a compact option when you need lighter carry weight or reduced magazine bulk. The rotary mechanism houses each round in its own chamber, which prevents rim overlap and the feeding issues that plague traditional stack-style magazines.
Ruger BX-1-5 Build Quality
Construction starts with a tough polymer body paired with steel feed lips. This combination has proven itself across thousands of rounds at ranges and in the field. The rotary design maintains precise cartridge alignment, and that metal feed lip assembly is engineered to handle repeated loading cycles without developing the wear or deformation you might see from lower-quality alternatives. Ruger built this to the same exacting tolerances as their larger capacity BX-1 models.
Compact Profile and Compatibility
The 5-round capacity makes the BX-1-5 noticeably more compact than the 10-round standard. It fits flush with the 10/22 mag well and works across the entire Ruger rimfire platform including SR-22 rifles, 22 Charger pistols, American Rimfire rifles, and 77/22 models. Because it's a factory Ruger magazine, fitment is guaranteed regardless of whether your rifle is from 1964 or yesterday.
When to Grab This Magazine
The 5-round capacity shines for situations where low-profile is valuable or where you simply want a lighter mag in your range bag. It's a smart choice for backup mags, training sessions where frequent mag swaps make sense, or anyone who prefers a more compact solution without sacrificing the reliability of Ruger's proven rotary mechanism.

Frequently Asked Questions
Will the BX-1-5 work in older 10/22 rifles?
Yes. Ruger 10/22 magazines maintain backward compatibility across the entire product line regardless of manufacture year. The BX-1-5 will function in any factory original 10/22 rifle from the earliest models to current production.
How does the rotary design compare to standard stack magazines?
The rotary mechanism places each .22 LR round in its own indexed channel, preventing the rim overlap and stacking friction that causes failures in traditional box-style magazines. This design keeps rounds properly aligned as they feed up toward the chamber, delivering more consistent performance especially with different ammunition types.
Is the BX-1-5 worth getting if I have 10-round magazines?
It depends on your needs. The 5-round capacity makes it lighter and more compact for backup mags or range days where you prefer minimal weight and profile. Both are equally reliable factory Ruger products, so the choice comes down to whether you need the extra capacity or prefer the low-profile package.
What makes factory Ruger magazines better than aftermarket options?
Factory Ruger magazines are engineered to Ruger's exact specifications and use the same materials as their firearms. This precision fit and quality control means fewer feeding issues and longer lifespan compared to many third-party alternatives, particularly with the proven rotary design used in the BX-1-5.
