Built for harsh use: materials and finish

The PROMAG AR-15 magazine uses a heat-treated steel body with a black oxide finish to resist wear and provide a low-reflective surface suitable for tactical environments. Heat-treated steel gives the magazine impact and dent resistance superior to many stamped or polymer-only designs, while the black oxide finish adds corrosion resistance without adding bulk.

Feeding system and spring technology

Chromesilicon wire spring

This magazine employs a chromesilicon wire spring engineered for consistent spring tension and long life. Chromesilicon alloys resist sag and maintain reliable follower pressure through repeated loading cycles — a critical trait for high-rate drills, training days, or duty use.

Precision-molded polymer follower

The precision-molded polymer follower ensures smooth, consistent alignment of cartridges into the feed ramp. Combined with the chromesilicon spring and heat-treated body, this follower reduces the chance of nose-dives and misfeeds when running rapid reloads.

Caliber compatibility and practical applications

This magazine is specified for AR15 rifles chambered in .223 Remington / 5.56 NATO, a caliber known for manageable recoil, wide ammunition availability, and suitability across training, competition, and defensive roles. Using a magazine matched to this chambering ensures reliable chambering of both .223 and 5.56 loads when appropriate.

Value and procurement

At a street price of $20.99, the PROMAG AR-15 offers a cost-effective spare or rotation magazine for range bags and patrol kits. The Promag name is recognizable for offering practical, budget-minded solutions; the model variety gives users options depending on capacity and mission needs.
