JG15 ULTRALIGHT 300 Blackout Complete Upper Assembly – 8″
The Jacob Grey Ultralight Complete Upper Assembly was designed with the next generation AR-15 in mind. 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 7” free float 7-sided M-LOK handguard that is also lightweight and leaves plenty of room for customization or the addition of numerous accessories available for the AR-15 platform. This complete upper assembly is extremely reliable and smooth shooting.

While the 300 Blackout round is common, the ammunition used greatly affects the performance of your Jacob Grey Upper Receiver. We test our upper receivers using 145gr subsonic ammunition, this may not be the round you prefer to shoot. Buffer weight and spring coil tension greatly affects your firearms performance. You may need to adjust buffer weight accordingly to suit your choice of round. H2 and H3 Buffers are commonly used with the 300 Blackout caliber. If unsure about your firearms performance seek help from a qualified gunsmith.
