Toolcraft Titanium Series 5.56 Bolt Carrier Group

Ultra strong, Ultra lightweight!  

Toolcraft Titanium Series 5.56 Bolt Carrier Group is an ultra strong, ultra lightweight full-auto M16 BCG, manufactured using either a 9310 steel or Carpenter 158 steel bolt, and 6A1-4V Titanium carrier. This complete bolt carrier group weighs in at 7.84oz, a jaw dropping 32% weight reduction over a standard BCG!  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!
