JG15 300 Blackout Complete Upper Assembly – 8″
If you’re in the market for a complete upper assembly that performs in CQC/CQB and also doubles as an effective mid-range weapon, the Jacob Grey 8” 300 Blackout Complete Upper Assembly is just what you’re looking for. The Jacob Grey barrel is designed with a thicker wall to better handle excess heat while minimizing barrel whip. The increased strength, hardness, and high-temperature stability of 4150 Chrome Moly Vanadium barrels are better suited for full-auto and rapid fire. Our complete uppers come with a JG 7” M-LOK handguard giving you plenty of space for all the accessories you could want. The JG 3-Stage Muzzle Brake helps mitigate the recoil impulse and felt recoil.

**Disclaimer**
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.

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.
