Description
The WMD Guns NIB-X Bolt Carrier Group without hammer is a replacement bolt carrier group for AR-15 and M16 pattern rifles chambered in 5.56x45mm NATO and .223 Remington. It is built to cycle the action and carry the bolt assembly, and it is offered without the hammer, so the hammer must be supplied separately or transferred from the existing group.
The carrier is finished with a nickel boron coating, which the listing describes as harder than Tennifer, melonite, nickel Teflon and hard chrome, with a stated hardness of Rc72 and a low coefficient of friction of about 0.07. The listing also cites environmental corrosion protection and easier cleaning, with the coating wiping clean in most cases.
The group is silver in color and fits AR-15 and M16 5.56 rifles. Confirm the hammer and any other required parts are compatible with your receiver and fire control before installation.
