The Ruger 90521 77/17 WSM 6-round rotary magazine is OEM ammunition storage built specifically for the Ruger 77/17 WSM rifle platform. If you own a 77/17 in this caliber and want a reliable, factory-backed spare magazine or need to keep multiple magazines loaded and ready, this is the magazine Ruger engineered for your rifle. It's the straightforward choice when you need to know a magazine will function exactly as your rifle was designed to use it.
The magazine body is constructed from polymer, a material choice that keeps weight minimal while resisting corrosion—useful whether you're hunting in wet conditions or storing magazines long-term. Steel feed lips handle the mechanical work of reliably presenting rounds to the chamber, and the 6-round capacity fits the practical needs of field shooting and hunting workflows.
Ruger factory magazines are manufactured to the same tolerances as the magazines that shipped with your rifle, eliminating the guesswork that comes with aftermarket options. This is especially important in a precision rifle platform like the 77/17, where feeding reliability directly affects accuracy and shot placement.
