First Impressions of FailZero 6mm ARC Bolt Carrier Group
The 6mm ARC, or Advanced Rifle Cartridge, has quickly gained popularity for its impressive long-range capabilities in the AR-15 platform. When building a new 6mm ARC AR, or upgrading an existing one, the bolt carrier group (BCG) is a critical component. The FailZero 6mm ARC Bolt Carrier Group promises enhanced reliability and ease of maintenance thanks to its EXO Nickel Boron coating.
For years, I’ve been building and tweaking AR platforms for various applications, from hunting whitetail in dense Pennsylvania forests to participating in local precision rifle competitions. I was drawn to the FailZero 6mm ARC Bolt Carrier Group seeking a BCG that could offer consistent performance and effortless cleaning, ultimately reducing downtime and maximizing range time. I’ve spent countless hours cleaning standard mil-spec BCGs. The promise of “permanent dry lubricity” piqued my interest immensely.
Upon unboxing, the FailZero BCG presents a clean, silver finish that is characteristic of its EXO Nickel Boron coating. The coating appears evenly applied, and the entire assembly feels solid and well-built, exhibiting none of the machining marks or rough edges sometimes found on budget BCGs. The weight is comparable to other standard M16-cut BCGs, contributing to a familiar feel when handling.
Compared to standard phosphate-coated BCGs, the FailZero immediately stands out with its smoother, more refined appearance. Against a similar nickel boron BCG from a different manufacturer, the FailZero‘s coating appears slightly more polished and even. This visual difference translated into a smoother action when racking the charging handle in my upper receiver.
I was immediately impressed and optimistic about the potential performance gains and ease of maintenance that the FailZero 6mm ARC Bolt Carrier Group could offer.
Real-World Testing: Putting FailZero 6mm ARC Bolt Carrier Group to the Test
First Use Experience
The initial testing took place at my local outdoor shooting range on a clear, cool autumn day. I installed the FailZero 6mm ARC Bolt Carrier Group into my newly assembled 6mm ARC AR-15, paired with a 20-inch barrel and a quality optic. I fired approximately 200 rounds of various 6mm ARC ammunition, including Hornady ELD Match and some factory-loaded hunting rounds.
The FailZero BCG performed flawlessly from the very first shot, exhibiting smooth cycling and consistent extraction. Even with rapid firing, the action remained smooth and consistent, showing no signs of binding or hesitation. No cleaning or lubrication was applied prior to initial use to truly test the “dry lubricity” claims.
The real test came during the cleaning process after the range session. Carbon fouling wiped away with minimal effort using only a dry cloth, significantly reducing the time and effort required compared to cleaning a standard mil-spec BCG. The ease of cleaning alone made a positive impact.
Extended Use & Reliability
After several months of regular use, the FailZero 6mm ARC Bolt Carrier Group continues to impress. I’ve put several hundred more rounds through it, across various range days and one weekend hunting trip. The BCG has been subjected to temperatures ranging from near-freezing to moderately warm, and has been exposed to some light rain and dusty conditions.
The EXO Nickel Boron coating has proven to be exceptionally durable, showing minimal signs of wear and tear despite consistent use and cleaning. There are some very minor scratches on the bearing surfaces. However, the coating has held up remarkably well and has not chipped or flaked off.
Maintaining the FailZero BCG remains incredibly simple. A quick wipe down with a cloth and occasional light brushing is all that’s needed to keep it running smoothly. Compared to my previous experiences with phosphate BCGs, where carbon fouling often required aggressive scrubbing and solvent soaking, the FailZero has been a game-changer. It performs as advertised and has become a time-saving addition to my firearm maintenance routine.
