PROMAG MAG AR-308 LR-308 SR25 308WIN 10RD STEEL

The PROMAG 10-round steel magazine for AR-308, LR-308, and SR25 pattern rifles gives you a reliable, compact feeding solution for .308 Winchester platforms. Built from phosphate steel, this mag handles the demands of the range, competition, or field without the bulk of a 20-rounder—making it ideal for hunters and tactical shooters who value maneuverability and quick magazine changes in tight situations.

Designed to work with DPMS LR-308 and SR25 pattern firearms, the PROMAG 10-rounder fits the modern .308 AR platform ecosystem. Whether you're running precision loads for long-range hunting, testing loads at the bench, or training with your precision rifle, a 10-round mag keeps your profile low and your handling nimble. The steel construction resists corrosion and abuse better than polymer, making it a tough choice for guys who run their gear hard.

Pro Mag engineered this mag for shooters who don't need maximum capacity but demand consistent function. Ten rounds is legal in most hunting scenarios, practical for bolt-action muscle memory, and genuinely useful in vehicles or tactical situations where a smaller footprint matters. If you're building a .308 AR setup or looking for a backup mag that doesn't compromise reliability, this is a no-nonsense choice.

Frequently Asked Questions

Will this magazine work with my AR-308 or LR-308 rifle?

Yes—the PROMAG 10-rounder is engineered to feed reliably in DPMS LR-308 and SR25 pattern rifles. If you're unsure whether your .308 AR follows one of these patterns, check your upper receiver or ask us; we're happy to confirm fit before you buy.

What's the advantage of a 10-round mag over a 20-round?

A 10-round magazine is lighter, more compact, and easier to stow in a pack, vest, or vehicle. It's also legal for hunting in many regions where higher-capacity mags are restricted. For bench shooting, hunting, or training scenarios, ten rounds is often all you need between magazine changes.

Is the phosphate steel finish durable for field use?

Phosphate steel is a time-tested finish that resists rust and corrosion well, and it stands up to rough handling. It's a practical choice for mags you'll actually use in the field rather than keep in a safe.
