Fail Zero 6.8 GRENDEL EXO Nickel Boron Bolt Carrier Group - BCG

Not all Nickel Boron is created equal and FailZero is the undisputed pioneer of Nickel Boron technology. When failure is not an option, you can depend on FailZero.

The 6.5 Grendel Bolt Carrier Group is fully assembled and drop-in ready for most MIL-SPEC upper receivers. All critical parts are coated with EXO Nickel Boron technology providing permanent dry lubricity, extreme durability and increased wear and corrosion resistance. This patented Nickel Boron coating will reduce friction and improve the overall performance of your rifle.

Safety Note: Choosing 6.5 Grendel comes with an added complication. There are “Type I” and “Type II” bolt/barrel specifications out there, and you CAN NOT mix and match parts for each of them without risk of damage and/or injury. Type II is by far the most popular configuration, but pay attention to what you are buying! A Type I bolt won’t chamber rounds in a Type II barrel at all. Even worse, a Type II bolt mated to a Type I barrel will create excessive headspace and result in a rifle that is dangerous to fire.

    Nice BCG but failed final QC.

    I was looking for an NiB BCG with a matte finish and there are not a lot of options so I gave FZ a shot. Overall the BCG seems well made and the NiB finish seems well applied. The carrier had a pretty significant ding on the lower bearing rail and I am guessing was there before the NiB was applied. This is not the first FZ product I have had issues with either but with limited options I figured it was worth a try. RTB was quick to issue an RMA for a refund so no problems there. FZ needs to up their QC game. I would like to give them 5 stars.

    FZ NiB Grendel II BCG

    Appears to be very well made. Bolt mics in spec and stays put upside down, unlike John Paul's bolt witch uses one piece gas ring. Haven't put any rounds on it yet.
