Description
This is a factory Ruger rotary magazine built to match the exact specifications of the original equipment magazines that ship with the American Rifle. Made from lightweight polymer with matte black finish, it sits flush with the stock and pairs naturally with your rifle's ergonomics. The rotary design feeds cartridges directly in line with the bolt instead of offset, which keeps things running smooth and consistent whether you're at the range or in the field.
Real Factory Parts, Real Reliability
Ruger manufactures this magazine to the same tolerances and standards as the OEM magazines, which means fit and function line up perfectly with your American rifle. The steel feed lips prevent binding and ensure reliable feeding across extended shooting sessions. The polymer follower and black matte finish are engineered to hold up through normal use while keeping things lightweight compared to steel alternatives.
Low-Profile Design for Balance
The flush-fit profile means this magazine doesn't extend below the stock line, preserving the rifle's handling and balance. It works with any long-action American Rifle stock that has a removable magazine well assembly, making it a straightforward drop-in replacement or reliable backup magazine. At just 0.15 lb, it adds minimal weight while giving you extra ammunition capacity where you need it.

Frequently Asked Questions
Will this magazine fit my Ruger American short-action rifle?
No, this is strictly a long-action magazine for .270 Winchester and .30-06 Springfield calibers only. Ruger American rifles come with different magazine patterns depending on caliber and action type, so verify your rifle's specs before ordering. Using the wrong magazine type can cause feeding issues or failure to chamber.
Is the Ruger American rotary magazine interchangeable with other factory rifles?
This magazine is specifically designed for Ruger American long-action rifles and fits stocks with a removable long-action magazine well assembly. It won't work with other rifle brands or Ruger platforms. The rotary design is proprietary to the American Rifle system.
How does the rotary magazine design compare to standard box magazines?
The rotary mechanism feeds cartridges directly in line with the bolt rather than offset from the side like a traditional box magazine. This straight-line feeding reduces binding and creates smoother, more reliable feed cycles. Rotary magazines are also typically more compact and hold their profile well in the stock.
Can I use this spare magazine as a direct replacement if my original magazine breaks?
Yes. This is a factory Ruger magazine manufactured to the exact same specifications and tolerances as the OEM magazine, so it'll perform identically. Many owners keep one or two spares on hand since magazine springs and followers can wear with heavy use over time.
