Palmetto State Armory
Overview
The Premium 5.56 Nickel Boron Bolt Carrier Group (BCG) from Palmetto State Armory is designed specifically for 5.56 NATO caliber builds, providing enhanced durability and ease of cleaning thanks to its Nickel Boron finish. This finish not only reduces friction but also helps in resisting corrosion, making it a reliable choice for builders who value performance and longevity. You’ll commonly find this BCG in mid-length gas system builds, where reliability and smooth operation are essential.
