The ProMag AR15 5.56 40rd Steel/Polymer Hybrid Magazine is purpose-built for shooters and operators who demand reliable ammunition capacity without sacrificing durability in field conditions. Designed specifically for AR-platform rifles in 5.56 NATO/.223 Remington, this 40-round magazine extends your engagement window in both tactical and recreational shooting scenarios. Whether deployed for duty, competition, or high-volume range sessions, this hybrid construction balances weight management with the structural integrity required for professional-grade performance.

The steel and polymer hybrid design leverages the best of both materials: a reinforced steel feed lips and body components ensure consistent round feeding and resistance to impact damage, while strategic polymer integration reduces overall weight and enhances ergonomic handling. This construction methodology is favored by law enforcement and military units because it delivers the durability of all-steel magazines without the added carrying burden over extended operations. The 40-round capacity provides significant firepower for defensive roles and three-gun competition without introducing the feeding reliability concerns sometimes associated with overstuffed alternatives. Measuring 5 x 2 x 12.5 inches and weighing just 0.75 pounds loaded, the magazine maintains a low profile suitable for tactical plate carriers and load-bearing systems.

This magazine is fully compatible with all standard AR-15 platforms chambered in 5.56 NATO or .223 Remington, making it a versatile addition to any modern rifle configuration. Operators running Mil-Spec or commercial buffer tubes will find flawless performance with both mid-length and carbine-length gas systems. For duty carry, training scenarios, or backup magazine provisioning, the ProMag AR15 5.56 40rd hybrid design delivers the round count and reliability that experienced shooters have come to expect from this trusted brand.
