Ally Munitions Testing & Notes

At Ally Munitions, all magazines we offer are field-tested and vetted internally before they ever go live. Wade has personally run multiple sample sets of the DURAMAG 15-round mag across different ARC platforms and has been consistently impressed with its performance.

That said, we’ve never seen an ARC magazine that runs 100% of the time at full capacity across all platforms. This is true across manufacturers. As a best practice, we recommend downloading the magazine by 1–2 rounds when running 6mm ARC, 6.5 Grendel, or .22 ARC to improve bolt catch reliability and feeding consistency.

For most use cases—especially in hunting or field roles—this magazine offers a strong combination of reliability, build quality, and real-world practicality.

Disclaimer

Performance may vary depending on firearm configuration. Reliability can be influenced by factors such as your lower receiver tolerances, bolt catch design, and BCG geometry. We highly recommend testing this magazine in your own setup before relying on it in mission-critical scenarios.

We have not yet tested this magazine with the .338 ARC cartridge.
