Fz 6mm Arc Bcg No Hammer Nib

The FailZero 6mm Arc Bolt Carrier Group with no hammer is a drop-in, fully assembled component designed for precision rifle builds and tactical applications. It is engineered for operators running modern intermediate cartridge platforms, particularly those utilizing the 6mm ARC cartridge. This BCG is ideal for shooters who demand reliability and performance in harsh environments.

Constructed with FailZero's proprietary EXO Nickel Boron Technology, this bolt carrier group features a permanent dry-lubricity coating that eliminates the need for traditional lubricants. This coating significantly extends the lifespan of the component while providing extreme durability against wear, reducing fouling buildup, and enhancing corrosion resistance. The monolithic construction ensures uniform stress distribution and tighter tolerances, resulting in consistent cycling and reliable feeding.

This carrier is particularly beneficial for precision shooters, law enforcement units, and military personnel who build or maintain their own platforms. It is designed for compatibility with standard 6mm ARC upper receivers, making installation straightforward—simply seat the assembled group into the upper receiver for immediate use.
