Mercury Precision LR-308 Complete Bolt Carrier Assembly Nickel Boron Finish 

- .308 WIN/6.5 Creedmoor/.243 WIN



This Mercury Precision Nickel Boron Coated LR-308 BCG is Compatible with 6.5 Creedmoor, .308 Win , .243 Win & All Similar Calibers.

Mercury Precision Has Made This BCG Using the Highest Quality Materials

Fully assembled and ready to drop into your .308 Build. Carrier is made with 8620 hardened steel 

The Bolt Head is Made from 9310 Vac-Arc Premium Carburizing Steel which has a high core hardness and high fatigue strength unlike standard Hot/Cold rolled 9310 steels. 

This bolt carrier assembly has enhanced features for those looking to complete an Upper Receiver set up or to simply replace an existing bolt carrier group. The Nickel Boron coating has a rockwell hardness value of 74 giving it almost the same strength as a Nitride BCG but also provides the self-lubricating exterior allowing this BCG to run smoother while being able to be cleaned easier. This BCG still requires necessary lubrication and/or oil. This finish will not peel or flake.
