Description
This Ruger AI-style magazine is a genuine factory chassis mag designed to work with precision rifle platforms that accept AI-pattern bottom metal. The 60% glass-filled polymer body delivers strength and durability without excessive weight, while the stainless steel spring resists corrosion and keeps rounds feeding reliably shot after shot.
AI-Style Design Built for Field Use
The polymer construction keeps this magazine lightweight and impact-resistant, making it practical whether you're running it on the range or carrying it in the field. The stainless steel components won't rust or degrade from exposure, and the compact profile works well with precision setups. A dust cover ships with the magazine to protect rounds during transport and storage.
Multi-Caliber Compatibility
This 5-round magazine works with .308 Winchester, 6.5 Creedmoor, .243 Winchester, and other .308-sized cartridges. It fits Ruger Precision Rifles and Ruger Gunsite Scout Rifles chambered in these calibers, plus any other rifle with compatible AI-style bottom metal assemblies. If you shoot multiple .308-sized calibers from different rifles, a single mag design simplifies gear management.
Made in the USA
Ruger manufactures this magazine to factory tolerances, ensuring consistent fit and function with your rifle. The design is straightforward and built for practical use without unnecessary complexity. Each magazine includes the Ruger logo and comes finished in black.

Frequently Asked Questions
Will this AI-style magazine fit my Ruger American rifle?
If your Ruger American is fitted with an AI-style bottom metal assembly (AICS pattern), this magazine should work. Some Ruger American models come with flush-fit magazines instead, so check your rifle's mag well compatibility first. Ruger does make versions specifically for the American Predator Gen II with AI-pattern bottom metal.
Can I use this 5-round magazine in different calibers?
Yes, this magazine feeds .308 Winchester, 6.5 Creedmoor, .243 Winchester, and other .308-sized cartridges. The AI-pattern design is caliber-agnostic for short-action .308-sized rounds, so you can swap it between rifles chambered in these calibers as long as they have compatible bottom metal.
What's the difference between the polymer and steel versions?
Ruger offers both polymer and steel AI-style magazines in 5-round capacity. The polymer version weighs less and resists corrosion through its stainless steel spring and cover. The steel version (model 90352) offers heavier construction but adds weight. Both feed reliably and use the same AI-pattern interface.
Does the dust cover stay on during shooting?
The dust cover is designed to snap on and off for easy removal. You'll take it off before loading the magazine into your rifle. It's meant to protect your spare magazines during storage and transport, keeping dust and debris off the rounds until you need them.
