Jacob Grey Firearms Ultralight Complete Upper Assembly 5.56 NATO 16in Black

Jacob Grey Firearms Ultralight Complete Upper Assembly 5.56 NATO 16in Black. This AR-15 complete upper assembly is built around the 7075-T6 billet upper 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 AR-15 platform. It comes standard with the JG designed free float 7-sided M-LOK hand-guard that is also lightweight and leaves plenty of room for customization or the addition of numerous accessories available for the AR-15 platform. The barrel is chambered in 5.56 NATO with a 1:7 twist rate. The barrel is machined from 4150 chrome moly steel and black Nitride finished for corrosion resistance and accuracy. Each barrel is individually head-spaced to the Carpenter 158 bolt. Combined with the 8620 steel carrier and black Nitride finish this complete upper assembly is extremely reliable and smooth shooting.
