ArmorLube Coating:

Revolutionizing MILSPEC standards, the advanced DLC coating, ArmorLube, is the result of a decade-long collaboration with the US Army DEVCOM. Proven to drastically enhance reliability, prevent galling, corrosion, and seizure, this coating sets a new benchmark. In the taper abrasion test, ArmorLube outperformed with an exceptional 97,000 cycles, surpassing Nitride (25,000 cycles) and phosphate/Parkerizing (690 cycles).

Gas Key:

Precision torqued and staked, our gas key features optimized carrier key screws, virtually eliminating the risk of the key coming loose. A carefully applied sealant between the gas key and carrier ensures a gas-tight seal, addressing a common issue and preserving power and reliability.

Bolt:

Crafted from Carpenter 158 steel, featuring superior corrosion resistance, tensile strength, and fatigue resistance. This high-performance material ensures a smoother surface finish and enhanced wear resistance, making it the ideal choice for those who demand the highest quality and longest-lasting components.

Carrier:

The 8620 M16 carrier, precision ground to exacting tolerances, stands as a testament to our commitment to perfection. Skids ground to a flawlessly flat surface eliminate uneven wear, reducing friction and enhancing longevity.

Gas Rings:

Our SP4-coated gas rings redefine longevity. Lasting 3-4 times longer than standard rings, they significantly reduce friction, ensuring optimal performance even after extensive use.

Firing Pin:

Chrome-plated for additional durability, our firing pin ensures reliable ignition over an extended period, contributing to the overall longevity of the Bolt Carrier Group.

Rubber Gasket:

The inclusion of a rubber gasket for the extractor further exemplifies our dedication to reliability in every aspect of the extraction process. Guaranteed to perform, the MD Enhanced Bolt Carrier Group is not just a component; it's a precision-engineered solution that empowers your M4 weapon system with unparalleled reliability, durability, and performance. Elevate your firearm experience with the assurance that our product is designed to exceed expectations in any environment.
