DuraMag SS 20-Round 6.5 Grendel/6mm ARC AR-15 Magazine - Black Stainless Steel

The DuraMag SS 20-Round 6.5 Grendel/6mm ARC AR-15 Magazine is a stainless steel magazine purpose-built for shooters who run modern intermediate cartridges in AR-platform rifles. Whether you're developing handloads for 6.5 Grendel, pushing the ballistics envelope with 6mm ARC, or simply tired of plastic magazines that warp and fail at the worst moments, DuraMag's steel construction delivers the durability your rifle deserves.

Plastic magazines absorb moisture, distort under temperature swings, and lose spring tension over time—none of which is acceptable when reliability matters. This DuraMag addresses those shortcomings with stainless steel construction that shrugs off humidity, extreme cold, desert heat, and years in the safe without degradation. The Everflex spring maintains consistent feeding pressure through thousands of cycles, while the blue AGF follower seats rounds smoothly and supports reliable extraction every time.

A 20-round capacity strikes the practical balance for precision shooting and hunting with either caliber. The magazine works seamlessly with any AR-15 lower receiver configured for 6.5 Grendel or 6mm ARC, making it a straightforward upgrade whether you're building a dedicated platform or swapping between upper assemblies. DuraMag's philosophy is simple: a firearm is only as dependable as its magazine.

Frequently Asked Questions

Will this magazine work with my 6.5 Grendel or 6mm ARC rifle?

Yes. This magazine is designed specifically for 6.5 Grendel and 6mm ARC cartridges in AR-15 platform rifles. Verify that your lower receiver is configured for one of those calibers.

Why stainless steel instead of plastic?

Plastic magazines absorb moisture and become brittle in cold, warp in heat, and lose spring tension after extended storage or use. Stainless steel resists all those failure modes, maintaining reliable feeding in any climate or after years in the safe.

How many rounds does it hold?

This magazine holds 20 rounds and is optimized for the ballistic profile and dimensions of 6.5 Grendel and 6mm ARC ammunition.
