My buddy Bobby over at Harris Tactical forgot to tell me about this pre-order he has going. Gonna have to talk to that guy! LoL! If you want to get your hands on a new NiB-X Full Auto Bolt Carrier Group before the year 2015 this is great option. Bobby has been working his butt off to keep his parts at the pre-panic prices and he’s doing a great job at it. These complete Nickel Boron Full Auto BCG’s are just $199 which is exactly the same if not a bit less than you would have paid for one 3 months ago. This is a pre-order and delivery is expected sometime late February or into March. Please support this great Veteran Owned business and pre-order your NiB-X BCG from HarrisTactical.com.
These AR15 Bolt Carrier Groups feature Harris Tacticals’s NiB-X Nickel Boron Coating, which provides extreme durability, performance, and reliability. The Nickel Boron coating is corrosion resistant and harder than Nickel Teflon, Melonite, or Hard Chrome with a hardness of RC 72. Cycling is smoother and debris and buildup can simply be wiped free.
Components included in the Assembly are mil-spec and manufactured by US suppliers. The Bolt assembly is case hardened, shot peened, magnetic particle inspected, and constructed of Carpenter 158 steel. The extractor includes a high performance spring and black buffer. The AR-15 style Carrier is machined from 8620 steel, heat treated, and case hardened. Attachment of the Gas Key is done with grade 8 hardened fasteners, which are staked per mil-specs. The Gas Key is sealed with the proper gasket as well. Bolt Carrier Group is also available with a Nickel Boron coated mil-spec AR15 Hammer. The NiB-X Hammer ensures the smoothest cycling possible.
SPECS: Fits AR15 mil-spec upper receivers.
