KCI USA Magazine Features The KCI USA magazine feeds reliably thanks to its patented stainless steel internal feed lips and increased-power spring both engineered to resist wear and maintain consistent feeding pressure across the full 30-round capacity. An anti-tilt follower keeps cartridges properly aligned as they rise through the magazine body reducing the chance of feeding malfunctions during rapid strings of fire. The polycarbonate body is manufactured to close tolerances so it drops freely into AR-15 M16 and M4 pattern lower receivers without binding. Steel-reinforced feed lips add durability at the point of the magazine that sees the most wear over repeated reloads. A textured exterior surface gives shooters a confident secure grip when inserting or stripping the magazine during a reload even with gloved hands. The translucent smoke housing lets users check remaining round count without disassembly and dual markings printed on both sides make that check possible from either side of the magazine. Weighing just over four ounces it adds minimal bulk to a plate carrier or range bag while still holding a full 30-round load. For shooters building out a set of spares for their AR-15 this magazine offers dependable capacity at an accessible price.
