Flat Dark Earth DLC Bolt Carrier Group (5.56mm / .300 BLK)

Our M16-profile 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, and 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). For added long-term reliability, our gas keys are staked using OCKS screws (Optimized Carrier Key Screw) which feature sharp, deep, effective knurling to ensure superior staking.

    Walker Defensive Research 300BLK BCG

    I’ve got the walker defensive research boat carrier group to replace a more expensive bCG that has failed after only 3,000 rounds. I had my gunsmith install it while was tubing up my rifle and try to repair my other BCG. when the Eakjee BCG arrived, I had a few days to check it out, take it apart and really get familiar with it. The workmanship was flawless and it rivaled my more expensive BCG in aesthetics. The quality of the build is obvious and reflects the premium nature of the product. I shoot virtually day when I’m at home, so it wasn’t long before I got to rub the walker I. My suppressed 14.5” 309 BLK. It oerforned flawlessly. It was slightly heavier than by previous BCG, but the weight difference is hardly noticeable. I will say that it Felt as though the Walker BCG Cycled more smoothly and didn’t tend to slam against the back of the receiver S hard as my previous one. It does not like to cycle subsonic rounds; but this is more a shortcoming of my rifle (a gas gun), And indeed, of the 300 BLK itself. I had hoped it might eliminate my fail-to-feed issues. While it certainly felled, I wish I could shoot subs without having to manually cycle every round or risk not having a rod chanbered when I squeeze the trigger to make a long shot on on a big hog. It was roughly as reliable as my other BCG, which is about 30% on subs. Through a 14.5’ smbattemm with a surefiee by BB In like my other BCG, the Walker is pretty easy to cycle manually and chambers subsonic rounds wit about 85-90 percent in this manner. It is 100% reliable so far on chambering supersonic ammo.. After approximately ?I would definitely recommend the Walker 309 BLK when reliability is of paramount importance - particularly with supersonic ammo.

    FDE DLC BCG

    The customer service I've received from the folks at Waler Defense has been incredible. I needed some advice on my current setup and they took the time to speak with me and assist me with my build. I was really excited to try this BCG out and took it out to run it as soon I received it and it ran flawlessly and was exactly what I needed to fix my problem. Highly recommend!
