Spikes Tactical AR15 Complete Full Auto Bolt Carrier Group w/ Nickel Boron Coating - 5.56MM. Comes Complete with Bolt Carrier, Complete Bolt, Cam pin, Firing Pin and Firing pin retaining pin.
Nickel Boron has proven itself to be the Most durable finish on the market. It's so good that it's being adopted by the Military and many Government agencies. It will Never chip, peal, or flake off. It's much smoother than Hard Chrome, it's easier to clean and you can run it almost lube free for thousands of rounds due to it's self lubricating properties. These BCG's are a huge improvement over a Phosphated BCG, They are even an improvement over Hard Chrome. |
