Engineered for reliable performance with heavy (200+ grain) .300 Blackout ammunition, the Lancer® L5 AR-15 .300 Blackout 20-Round Advanced Warfighter Magazine features a translucent, hybrid polymer/steel design for lasting durability, and corrosion and chemical resistance. 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. Aggressive texturing on the exterior of the magazine offers lightning-fast mag changes and reliable handling—even with gloved hands. Plus, the removable polymer floorplate easily slides off, similar to a USGI magazine, for quick disassembly when cleaning and maintenance are required.
