The AC-Unity AR-15 M4 60-Round Polymer Magazine is a high-capacity solution engineered for serious shooters, tactical professionals, and competitive marksmen. Designed to feed both 5.56 NATO and .223 Remington ammunition, this quad-stack AR15 magazine significantly increases round count without the added bulk of a drum, offering extended firepower with improved maneuverability. Crafted from high-strength, impact-resistant polymer, the magazine is built to withstand rigorous field conditions and rough handling. The stainless-steel spring resists corrosion and fatigue—even during long-term storage. An anti-tilt follower supports smooth, consistent feeding in all conditions. This 60-round 5.56 magazine offers the performance of a military-grade component now available to civilian and professional markets alike.
