Free Shipping on all Toolcraft Bolt Carrier Groups!

We are extremely pleased to finally be able to offer a chrome bolt carrier group manufactured by Toolcraft! These BCGs exceeded all our expectations.

The combination of state-of-the-art coating technology and improved coating materials makes these the finest chrome bolt carrier groups ever manufactured.

The Physical Vapor Deposition (PVD) process is used to apply a very thin (~3 micron) layer of Chromium Nitride (CrN) to all parts. The result is a BCG with the classic look of traditional chrome but with significantly increased performance.

Chromium Nitride (CrN) benefits

  • Twice as hard as traditional hard chrome
  • Uniform thickness, no buildup in corners
  • Adhesion is superior to plating
  • Low coefficient of friction 

These chrome BCGs feature Mil-Spec Carpenter 158 bolts, M-16 full-auto profile carriers and the famous Toolcraft lifetime warranty.
