Our carriers come with a variety of options and are all manufactured to customer print and specifications within our facility in Marion, North Carolina.
We manufacture over 9,000 carriers per week each available with Chrome/Phosphate, Nickel Boron or machined to satisfy all our customers.
Toolcraft has the ability to offer a wide variety of calibers and styles of BCG’s. If you prefer to apply a special coating, we can machine your order to the specifications that are required to allow for the coating buildup. If you decide to use this method, please let our knowledgeable customer service personnel know your intentions and we will machine it correctly to your application. We can also sell just the carrier or a carrier with the key properly assembled and staked.
This BCG (and all other products over $35) ships for FREE.
The ToolCraft Bolt Carrier Group is the “Heart of an AR-15.” The bolt carrier houses the bolt and resets the hammer as it moves within the upper receiver. The carrier also bears the brunt of the gas pressure during operation. This pressure moves it back to cycle the firing mechanism, and its performance is crucial to the proper function of your firearm.
In addition to having an attractive chrome colored finish, the Nickel/Boron finished BCG has a low co-efficient of friction and is wear resistant. Due to the columnar structure of the Nickel/Boron, the ToolCraft NiBor BCG is naturally lubricious and hard (70C+, on Rockwell scale).
The ToolCraft Nickel Boron BCG is an M16 Full Auto (Preferred for most AR-15 builds)
