Let’s Talk About FailZero M16/M4 Bolt Carrier Group (BCG), No Hammer
The FailZero M16/M4 Bolt Carrier Group (BCG), No Hammer promises enhanced reliability and smoother operation for your AR-platform rifle. Manufactured by FailZero, this BCG boasts a slick Nickel Boron coating designed to reduce friction and improve performance. For years, I relied on standard, phosphate-coated BCGs, but I was increasingly frustrated with the amount of time spent cleaning and the occasional failures to extract after prolonged firing.
I needed a BCG that would not only withstand heavy use, but also simplify maintenance and minimize malfunctions. After researching various options, the FailZero BCG stood out due to its reputation for durability and ease of cleaning. Unboxing the FailZero, I immediately noticed the smooth, almost polished, Nickel Boron finish. The BCG felt solid and well-constructed, definitely a step up from the standard, rougher finish of my previous BCG.
Compared to a standard Mil-Spec BCG from Bravo Company Manufacturing (BCM) and a nitride-coated BCG from Daniel Defense, the FailZero’s slickness was immediately apparent. I chose the FailZero primarily for its ease of cleaning and enhanced lubricity. I was excited to see if the FailZero M16/M4 Bolt Carrier Group (BCG), No Hammer could truly deliver on its promise of improved performance and reduced maintenance.
Real-World Testing: Putting FailZero M16/M4 Bolt Carrier Group (BCG), No Hammer to the Test
First Use Experience
My initial testing took place at an outdoor range in the high desert of Nevada. The conditions were typical for the area: dry, dusty, and with temperatures hovering around 90 degrees Fahrenheit. I put the FailZero BCG through its paces with a mix of .223 Remington and 5.56 NATO ammunition.
The rifle cycled smoothly, and I experienced no failures to feed, fire, or extract during the first 200 rounds. The reduced friction from the Nickel Boron coating seemed to make a noticeable difference in the rifle’s overall operation. After the first range session, I was pleasantly surprised at how easily the carbon fouling wiped off the BCG.
Extended Use & Reliability
After several months of use, the FailZero BCG continues to perform admirably. I’ve put over 1000 rounds through it in various conditions, including rain, mud, and extreme heat. The Nickel Boron coating has held up well, with no signs of chipping or flaking.
Cleaning the FailZero BCG remains significantly easier than cleaning a standard phosphate-coated BCG. Even after prolonged use, carbon fouling wipes away with minimal effort. Compared to my previous BCGs, the FailZero has noticeably improved reliability and reduced cleaning time.
