Classified Defense - Ultimate M16 Bolt Carrier Group - 5.56x45MM - C158 - DLC/Chrome

We were finally able to source everything we wanted in a bolt carrier group. We have envisioned this bolt carrier group for many years, but due to the manufacturing processes at the time, we weren't able to get exactly what we wanted. Now, thanks to the culmination of some industry giants, we are able to provide you with exactly what we too have been waiting for. This is a spare no expense bolt carrier group. The best raw materials, the best manufacturers, the best coatings available, and the best in the world inspecting and assembling them. It simply is the ULTIMATE Bolt Carrier Group!

All Classified Defense Bolt Carrier Groups are inspected and assembled completely in-house.  If you know us, and you know how we do things, we accept nothing less than perfection! All of our bolt carrier groups are covered by an unconditional Lifetime Guarantee.
