The Stainless-Steel AR magazines are constructed with the highest level of quality that guarantees durability and longevity. Constructed from .020-gauge 410 Stainless-Steel Alloy that is heat treated for strength and endurance. A more reliable alternative to polymer magazines because they will not swell in heat or crack in the cold.

They are coated with Black Marlube, a durable, wear-in, not wear off, coating. This coating offers supreme performance, protection, and lubrication for your magazine. The more you use it, the better it performs.

This stainless-steel magazine has an enhanced anti-tilt polymer follower with PTFE, chrome silicon springs, and 300 series stainless steel floor plate with black oxide coating for corrosion resistance.

PTFE stands for Polytetrafluoroethylene, which is a synthetic fluoropolymer of tetrafluoroethylene. It has hydrophobic, non-wetting, high-density and resistant to high temperatures material. PTFE has a wide variety of applications and is known for its nonstick properties.

The 300 series stainless steel consists of austenitic chromium-nickel alloys which creates superior corrosion resistance and ease of fabrication. Black oxide is a conversion coating formed by the chemical reaction with the iron in a metal to form a protective surface.
