Description
This ASC 10-rounder is purpose-built for AR-15 rifles chambered in 6.5 Grendel. The compact capacity keeps things manageable for hunting, target work, or range days without the bulk of a magazine that overloads your setup. The stainless steel body resists environmental wear and won't swell in heat or crack in cold like polymer alternatives do, making it genuinely reliable across different conditions.
ASC Stainless Construction Built to Last
Every magazine is manufactured 100 percent start to finish in the USA using .020 gauge 410 stainless steel alloy that's heat-treated for superior strength and endurance. ASC applies a proprietary Marlube finish that works differently than typical coatings. Instead of wearing away with use, it burnishes into the surface and actually improves over time, providing self-lubricating properties that keep feeding smooth. The magazine is chemically treated for corrosion resistance and finished in matte black.
Proven Feeding Performance
The anti-tilt polymer follower with a bright blue color sits above chrome silicon springs that drive reliable feeding from the first round through the last. This combination keeps rounds properly aligned and moving forward with consistent pressure, which matters for a cartridge like the 6.5 Grendel where feeding requires precision. The stainless steel floor plate adds durability and drops free from the mag well when needed.
The Right Choice for the 6.5 Grendel
ASC's reputation in the 6.5 Grendel world is solid because they engineered these magazines specifically for the cartridge, not as an afterthought. They ship with a limited lifetime warranty and work in standard AR-15, M4, and M16 platform rifles. If you want a magazine that works hard without demanding constant maintenance, this one checks the box.

Frequently Asked Questions
Will this magazine work with my 6.5 Grendel AR-15?
Yes, it's designed specifically for AR-15, M4, and M16 platform rifles chambered in 6.5 Grendel. It uses the standard AR-15 lower receiver interface, so compatibility is straightforward. Just verify your mag well accepts standard AR magazines before ordering.
What makes ASC's Marlube finish different from other coatings?
Marlube is a wear-in coating that burnishes deeper into the surface the more you use it, rather than wearing away like typical finishes. This means the magazine gets more slippery and protective over time, enhancing performance through actual use.
How does the 10-round capacity compare to larger magazines?
The 10-round size keeps your profile compact and handling nimble, making it ideal for hunting, precision work, or casual range sessions. If you need higher volume, ASC makes this same magazine in 15, 25, and other capacities for different shooting applications.
Is the stainless steel body worth the extra weight compared to aluminum?
Yes. Stainless won't swell in heat or crack in cold like aluminum can, and it resists corrosion far better in humid or wet conditions. For long-term reliability, the slightly heavier weight is a fair trade.
