Description
The 6.5 Grendel demands purpose-built magazines, and the DuraMag SS delivers exactly that. This 26-round magazine is engineered specifically for the longer, more demanding geometry of the 6.5 Grendel and 6mm ARC cartridges. Where standard converted magazines often struggle with reliability, this purpose-designed mag feeds cleanly and consistently from the first round through the last.
DuraMag Stainless Steel Construction and Durability
Machined from 410 stainless steel and heat treated for maximum toughness, this magazine can take abuse that would destroy aluminum alternatives. The robotically welded post and hole design adds strength without adding unnecessary weight. You get a magazine that resists corrosion, won't flex or swell under stress, and maintains its shape through thousands of rounds. The T-360 Teflon coating covers the entire body inside and out, creating a slick surface that feeds smoothly while protecting against wear and harsh conditions.
Optimized Feed Geometry for 6.5 Grendel and 6mm ARC
The DuraMag SS incorporates LipLock technology that keeps each round positioned at the correct angle and height as it feeds. Paired with the blue Advanced Geometry Follower, this design ensures consistent, level feeding without the binding issues or jams that come with magazines designed for different cartridges. The EverFlex anti-fatigue spring maintains consistent pressure throughout the magazine's life, so it performs just as reliably when fully loaded as it does when partially filled. Real-world feedback from 6.5 Grendel users consistently reports flawless feeding and reliable lock-back on the last round.
What You Get
This is a magazine engineered to work. No shimming, no modifications, no workarounds. The internal room is generous enough to handle long cartridge loads, and the easy-loading design means you're not wrestling with stiff feed lips every time you charge the mag. Whether you're running precision loads for long-range shooting or rapid fire drills at the range, the DuraMag SS stays consistent.

Frequently Asked Questions
Will this DuraMag magazine work with 6mm ARC as well as 6.5 Grendel?
Yes. The DuraMag SS is specifically designed for both 6.5 Grendel and 6mm ARC cartridges. The internal geometry works with both rounds because they share similar dimensions and feed angle requirements. Many users run both cartridges through the same magazines without any issues.
How is this DuraMag different from using converted 5.56 magazines for 6.5 Grendel?
This is purpose-built for 6.5 Grendel, not a converted standard AR magazine. The feed lips, follower geometry, and internal dimensions are optimized for the Grendel cartridge's longer length and different pressure curve. Purpose-designed magazines feed more reliably and reduce jams and double-feeds that often occur with conversions.
Why is stainless steel worth it for a magazine?
Stainless steel won't flex or swell under stress like aluminum can, resists corrosion better, and maintains shape through extended use and storage. The DuraMag SS is heat-treated 410 stainless, which is tougher than standard stainless while staying relatively lightweight. You get durability that outlasts aluminum without significant weight penalty.
Can I overfill this DuraMag to hold 27 or 28 rounds?
The magazine is rated and engineered for 26 rounds. While some users report being able to squeeze in 27 rounds with effort, the spring was designed for 26-round loading. Overfilling can cause feeding issues and reduces the reliability of the spring, so stick with the rated capacity for consistent performance.
