MD Sand Cutter Bolt Carrier Group
Precision Engineering for Harsh Environments
- ArmorLube Coating: Advanced DLC coating developed with the US Army DEVCOM. Outperforms Nitride (25,000 cycles) and phosphate/Parkerizing (690 cycles) with 97,000 cycles in the taper abrasion test. Prevents galling, corrosion, and seizure.
- Gas Key: Precision torqued and staked with optimized screws. Sealed with Permatex gasket sealer for a gas-tight fit, ensuring reliability and power.
- Bolt: Made from Carpenter 158 steel for superior corrosion, tensile, and fatigue resistance. Provides a smoother surface finish and enhanced wear resistance.
- Carrier: 8620 M16 carrier, precision ground to exact tolerances. Features angled slots on the rails to cut through sand and debris and push it out.
- Gas Rings: SP4-coated for extended life, lasting 3-4 times longer than standard rings. Reduces friction for optimal performance.
- Firing Pin: Chrome-plated for increased durability and reliable ignition.
- Rubber Gasket: Ensures a reliable extraction process.
