Walker Defense Research Research Bolt Carrier Group (BCG) FDE-DLC-BCG-556 Color: Flat Dark Earth, Finish: DLC, $14.00 Off — Free 2 Day Shipping w/ code 2DAYAIR

The Walker Defense Research M16-profile Flat Dark Earth (FDE) Bolt Carrier Group features a carrier and gas key finished with IonBond's Flat Dark Earth DLC (Diamond-Like Carbon) coating. 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
