Toolcraft DLC 6.5 Grendel Bolt Carrier Group
Now with Diamond-Like Carbon (DLC) Coating!
Toolcraft DLC 6.5 Grendel Bolt Carrier Group is a Full-Auto M16 BCG, manufactured using a 9310 steel bolt, and 8620 steel carrier. The Diamond-Like Carbon Coating is a relatively new and highly desired coating for BCG’s. DLC has a very low coefficient of friction, is self-lubricating in dry conditions, extremely resistant to wear, highly resistant to corrosion, and one of the hardest coatings at 90 Rockwell. DLC is tough, hence the Diamond-like name, it features additional lubricity over Nickel Boron, and carbon fouling wipes right off with a dry patch. The Bolt Carrier Group is the heart of your rifle, and if you want a smooth running BCG that’s easy to clean, this is the one for you!
