LANTAC 308 Enhanced Bolt Carrier Group DPMS Nickel Boron
LANTAC 308 Enhanced Bolt Carrier Group DPMS Nickel Boron
The LANTAC 308 Enhanced Bolt Carrier Group is a DPMS-style bolt carrier group for .308 Winchester platforms, precision machined from 8620 steel with a 9310 precision hard ground bolt. Its patented UCT EXO Nickel Boron coating gives it an ultra-low friction coefficient of 0.02 and a surface hardness of 82-85 Rockwell C, so the action runs flatter with a smoother energy pulse.
That combination means cooler, cleaner operation with less maintenance, and reduced upper pressurization when the rifle is run suppressed. It is built for precision shooting setups that need consistent cycling and long service life.
