Description
This 5-round detachable magazine is built for the Ruger Precision Rifle platform chambered in .300 Winchester Magnum. Made in the USA by Accurate-Mag and engineered to Ruger's exact specifications, it delivers the same fit and reliability as the factory mags that ship with your rifle.
Ruger Precision Magazine Construction and Durability
You're getting a real steel magazine here, not polymer. The body is blued steel with a Teflon-coated black nitride finish that stands up to the elements and repeated use. The steel floor plate and precision-engineered feed lips ensure consistent cartridge pickup every time you cycle through rounds. A steel spring paired with a polymer follower keeps things running smooth without unnecessary weight.
Magazine Design for Single-Stack Feeding
The single-stack design means cartridges feed one at a time straight into the chamber. This configuration is a match for precision shooting where you want zero variables affecting round placement. At 3.850 inches overall length, it accommodates standard .300 Win Mag and .300 PRC ammunition, so you've got flexibility if your platform ever gets rebarreled. The magazine holds a solid 5 rounds without taking up excessive space in your rifle bag or being bulky on the gun.
Perfect Spare or Replacement
Whether you're building a spare magazine collection or replacing one that's seen hard use, this is the right part. It's a genuine factory accessory that fits without fuss and feeds without drama. Having an extra magazine means less downtime between loading sequences and the confidence that if one mag needs a cleaning cycle, you've got another ready to go.

Frequently Asked Questions
Will this Ruger Precision magazine work with my .300 PRC rifle?
Yes. This magazine is stamped for .300 Winchester Magnum but also works with .300 PRC cartridges because both use the same .532 inch magnum bolt face and share similar case dimensions. You can safely use it with either caliber in your Precision Rifle.
How does the single-stack design compare to double-stack magazines?
Single-stack magazines feed one round at a time in a vertical line, which is ideal for precision shooting because it simplifies the feeding process and reduces variables. Double-stack designs hold more rounds but add width and complexity. For the Ruger Precision Rifle platform, Ruger chose single-stack for reliability at longer ranges.
Can I use this magazine with other rifle brands?
This magazine is designed specifically for the Ruger Precision Rifle in magnum calibers. While it follows the AICS pattern, always verify compatibility with your specific rifle model before purchasing to ensure proper fit and feeding.
What makes Accurate-Mag a reliable manufacturer?
Accurate-Mag is the OEM supplier for multiple major rifle manufacturers including Ruger, Savage, Remington, and Colt. They build magazines to military specifications and have been the choice for precision rifles and sniper platforms for years, so this magazine carries real pedigree.
