JG 5.56 NATO High Polish Nickel Boron BCG
Description
This M16 Bolt Carrier Group drops right into your M16, AR15 or M4 platform rifle. Or any of the Jacob Grey JG-15 upper receivers. We source our components from manufacturers that meet or exceed our high expectations. All parts are machined and properly heat treated to Mil-Spec followed by complete Nickel Boron coating, then polished to a high shine so less oils and lubricants are needed to have your BCG function as it needs to.
Our Nickel Boron Bolt Carrier Group is specifically coated to allow your rifle to operate smoothly, be easily maintained, and work longer without unnecessary cleanings and field strips. Jacob Grey warrants our products against defects or malfunction to such a degree that if your product is defective in any way we will gladly replace it. Every component, from the extractor to the firing pin, is made with exacting specifications to meet military standards and provide the best control possible. The Jacob Grey High Polished BCG is engineered to fit and work with the AR15, M4, and as a M16 BCG.

JG ULTRALIGHT
The Jacob Grey Ultralight Rifle was designed with the next generation AR15 in mind. This AR15 rifle is built around the 7075-T6 billet lower receiver specifically machined and cut in areas where excess material was unnecessary and areas that see excess use and wear, reinforced and strengthened to give a sleek, refined look, without losing the classic lines of the AR15 platform. The same consideration was given to the matching billet upper receiver.
