The Lancer® L5 AR-15 .300 Blackout 10-Round Advanced Warfighter Magazine features a translucent polymer/steel hybrid design, specifically engineered for reliable performance with heavy (200+ grain) .300 Blackout ammunition. The one-piece steel feed lip design, combined with a high-tensile steel spring and anti-tilt polymer follower, ensures smooth, snag-free feeding performance, while aggressive texturing on the exterior of the translucent polymer body offers lightning-fast mag changes and reliable handling. Plus, the removable polymer floorplate easily slides off for quick disassembly when cleaning and maintenance are required.
