From the manufacturer

Walker Defense Research Research Steel Bolt Carrier Group BCG 5.56mm / .300 BLK DLC Flat Dark Earth. FDE DLC offers lower friction easier cleaning and better lubricity including a lower overall need for lubrication compared to a standard mil-spec manganese phosphate bolt carrier group. The bolt itself features black DLC and is MPI (Magnetic Particle Inspected). Walker Defense Research employs small-batch quality control to maintain high standards. BCG components are hand-matched to prevent tolerance stacking and ensure reliable cycling. Each bolt undergoes Magnetic Particle Inspection (MPI) to ensure integrity and performance. Enhanced gas key staking with premium OCKS screws from Michiguns further ensures dependable operation under sustained use. This BCG is compatible with direct impingement 5.56mm .223 Rem and 300 BLK AR-15 platforms. The combination of Flat Dark Earth and black DLC coatings not only provides functional advantages but also delivers a distinctive and durable aesthetic. Designed & Engineered to: - Provide enhanced lubricity with Flat Dark Earth DLC coating for smoother operation and reduced friction - Simplify maintenance with easier cleaning compared to standard mil-spec finishes - Function reliably in both semi-auto and full-auto AR-pattern rifles chambered in 5.56mm or 300 BLK - Enhance durability and reliability with premium OCKS screws for gas key staking Specifications for Walker Defense Research Research Bolt Carrier Group (BCG): Manufacturer: Walker Defense Research Color: Flat Dark Earth Finish: DLC Fabric/Material: 4130 Steel Carrier Material: 8620 Steel Bolt Material: 9310 Steel Caliber: 5.56x45mm NATO .300 AAC Blackout .223 Remington Gun Make: AR Platform Colt Gun Model: M16 M4 AR-15 Hand: Right Weight: 11.63 oz Country of Origin: USA Features of Walker Defense Research FDE DLC Bolt Carrier Group BCG Offer increased lubricity Make cleaning easier Be used in both semi-auto and full-auto AR-pattern rifles chambered in 5.56mm or 300 BLK Carrier Coating: IonBond Flat Dark Earth DLC Bolt Coating: IonBond Black DLC Compatibility: M16/ M4 / AR-15 Using Direct Gas Impingement (not for use in piston guns) Profile: Full Auto Style Carrier w/ Properly Staked Gas Key True Mil-Spec dimensions 4130 steel gas key with grade 8 staked screws 4140 steel extractor and cam pin Hard chrome ground 8740 steel firing pin Magnetic particle inspected (MPI) Package Contents: Walker Defense Research FDE DLC Bolt Carrier Group What firearm models does the manufacturer say Walker Defense Research Research Bolt Carrier Group (BCG) is compatible with?
