KAK Industry DBC AR-15 5.56/.223/300BLK Bolt Carrier Group - Phosphate/Chrome-Lined - MO-425-0510-043

Enhance the reliability and performance of your AR-15 with the KAK Industry DBC Bolt Carrier Group, engineered specifically for 5.56 NATO, .223 Remington, and .300 Blackout calibers. This precision-manufactured BCG features an innovative dead-blow counterweight design that optimizes cycling, allowing seamless operation with a standard 3 oz carbine buffer even when paired with forced reset triggers or similar systems.

Key Features and Benefits

• Dead-Blow Counterweight Technology: A floating weight in the carrier tail reduces felt recoil and improves reliability, eliminating the need for heavier H-series buffers in specialized trigger setups.
• Chrome-Lined Phosphate Finish: The carrier and bolt receive a durable mag phosphate coating with chrome lining in critical areas, delivering superior corrosion resistance, reduced friction, and extended service life under demanding conditions.
• High-Strength Materials: Machined from 8620 steel for the carrier and 9310 steel for the bolt, both ground to tight .0002-inch tolerances for smooth operation and consistent performance.
• M16 Full-Auto Profile: Provides enhanced mass and reliability while maintaining compatibility with semi-automatic AR-15 platforms.
• Downward Gas Venting: Strategic port placement minimizes gas blowback to the shooter, improving comfort during extended range sessions or suppressed use.
