AR 15 Stainless Steel 5.56 / .223 / .300BLK | Duramag

The DURAMAG SS AR Magazine is a heavy-duty stainless-steel magazine designed for AR-platform firearms chambered in 5.56 NATO, .223 Remington and .300 Blackout.

Built from premium 410 stainless steel, it combines exceptional durability with advanced internal geometry designed to support smooth and consistent feeding. Unlike polymer magazine bodies, the stainless-steel construction resists flexing and swelling, making it suitable for demanding use and extended loaded storage.

410 Stainless-Steel Construction

The magazine body is manufactured from premium 410 stainless steel for excellent strength and long-term durability.

Its rigid metal construction helps maintain consistent geometry around the feed lips and magazine body, even during extended use and storage.

T-360™ Total Coating Technology

DURAMAG's T-360™ coating covers the complete magazine body inside and out.

The coating helps provide smooth operation and loading while protecting the stainless-steel construction against demanding environmental conditions and long-term wear.

LipLock™ Technology

The proprietary LipLock™ feed-lip design helps keep cartridges securely retained and correctly aligned.

This supports consistent positioning as cartridges move toward the chamber.

Advanced Geometry Follower™

The Advanced Geometry Follower™ is designed to remain level as the magazine cycles.

Its geometry helps maintain consistent cartridge presentation throughout the magazine's capacity.

EverFlex™ Spring Technology

The magazine uses DURAMAG EverFlex™ anti-fatigue spring technology.

The spring system is engineered for long service life and dependable performance during repeated loading and unloading cycles.

Post & Hole™ Construction

DURAMAG's Post & Hole™ manufacturing system adds structural strength to the magazine body while supporting precise robotic welding.

This construction helps create a rigid and durable magazine suitable for demanding use.

Optimised for .300 Blackout

In addition to 5.56 NATO and .223 Remington, the DURAMAG SS is designed for .300 Blackout ammunition.

Its internal geometry is particularly well suited to .300 BLK cartridges, including longer overall-length loads and heavier subsonic ammunition.
