Lantac USA Firing Pin 6mm ARC - AR-15

The Lantac USA Firing Pin is a drop-in replacement pin purpose-built for the 6mm ARC cartridge in the AR-15 platform. Designed and manufactured by Lantac USA, this firing pin is also a direct fit for 6.5 Grendel bolts, making it a versatile spare for AR-15 rifles built around either intermediate cartridge.

The pin is machined from 8740 carbon steel and finished in hard chrome plating per MIL-STD-171 1.2.2.4, giving it a tough, corrosion-resistant surface that holds up to repeated firing-pin impacts. It is hardened to 45-49 HRC for long service life in the AR-15 bolt assembly. The natural finish reads as a clean silver look, and the pin installs as a direct replacement for the factory 6mm ARC / 6.5 Grendel2 firing pin.

Whether you are building a new 6mm ARC AR-15 or replacing a worn pin on an existing rifle, this Lantac USA firing pin is a purpose-fit component for AR-15 bolt carrier groups chambered in 6mm ARC or 6.5 Grendel. Made in the USA.
