New! Mitchell Defense Enhanced ArmorLube M16 5.56mm NATO/.300 BLK Bolt Carrier Group 611001 Color: Black, Finish: Anodized, Fabric/Material: Steel, $12.50 Off w/ Free Shipping

The MD Enhanced ArmorLube Bolt Carrier Group is engineered for extreme reliability, reduced friction, and exceptional wear resistance in 5.56 and .300 BLK platforms. Its ArmorLube surface treatment - an advanced DLC coating developed with U.S. Army DEVCOM - achieves 97,000 abrasion cycles, far surpassing nitride and phosphate finishes. This ultra-hard coating prevents galling, corrosion, and carbon adhesion, keeping the carrier running clean during extended firing sessions. A Carpenter 158 bolt pairs with a billet extractor and O-ring for consistent case control, while SP4-coated gas rings offer a 3-4x lifespan increase and reduced friction. The 8620 M16 carrier is precision ground to perfectly flat bearing surfaces for smoother operation and reduced wear. The gas key is Permatex-sealed, torqued to spec, and secured with OCKS-pattern staking. A chrome-plated firing pin and rubber extractor gasket further enhance reliability, making this BCG ideal for duty use, high-volume shooters, and suppressed configurations.
