Description
When you're running 6.8 SPC, your magazine choice matters just as much as your barrel. ASC has been delivering quality stainless steel AR magazines for years, and this 10-rounder is purpose-built to feed this powerhouse caliber reliably. Whether you're punching holes at the range, hunting, or working with handloads, this magazine handles all of it.
These are manufactured entirely in the USA using 410 stainless steel alloy that's heat-treated for strength and longevity. The material won't swell in heat or crack in cold, giving you consistency no matter the conditions. Every magazine gets chemically treated for corrosion resistance, so you're not babying it in storage.
Built with Components That Work
Inside, you'll find a chrome silicon spring paired with an enhanced anti-tilt polymer follower that prevents the rounds from tipping as the mag empties. That matters for last-round reliability and smooth feeding. The grey follower gives you quick visual feedback on mag status, which beats guessing when you need to reload. All of this sits behind a 300 stainless steel floor plate with matte black powder coating.
Precision Interior for Handloaders
If you're serious about 6.8 SPC, you probably load your own. ASC designed these with interior dimensions of 2.316" (plus or minus .002") that let you load to magazine length without compromise. That kind of precision makes a real difference when you're optimizing velocity and consistency across multiple rifles.
The proprietary Marlube finish coating is a wear-in, not wear-off coating that bonds into the surface and provides self-lubricating properties. It gets smoother with use, not worse. Ten rounds might seem compact compared to larger capacity options, but it keeps the mag profile manageable for hunting, bench shooting, or situations where you need lighter weight gear.

Frequently Asked Questions
Will this magazine work with 224 Valkyrie?
These are designed and optimized for 6.8 SPC. While some users report that 224 Valkyrie can function in them (since it's a necked-down version of 6.8 SPC brass), ASC specifically engineers these for 6.8 SPC dimensions and specifications. Always test thoroughly in your specific rifle before relying on it for critical use.
How does this stainless steel magazine compare to aluminum?
Stainless steel won't swell in extreme heat or crack in cold like some materials, making it more stable across temperature extremes. It's heavier than aluminum but more durable for rough handling. ASC's stainless builds maintain a slick action thanks to the Marlube coating, so you don't sacrifice smooth operation for durability.
Is this magazine suitable for handloaded ammunition?
Yes. The interior dimensions are precisely engineered to 2.316" (+/- .002"), which is generous enough for loaded-to-magazine-length handloads. Many precision loaders prefer these for that reason. Just verify your specific loads cycle reliably in your rifle before taking it to the field.
What if the magazine doesn't feed properly in my rifle?
Feeding reliability depends on multiple factors including your specific lower receiver, magazine catch, and ammunition. Test with several different ammo types before assuming a magazine issue. Some rare cases may benefit from minor feed-lip adjustment, but most users report flawless function out of the box. If you experience issues, contact the seller about warranty or exchange options.
