8.5" 300 BLACKOUT Stainless Mid-Weight Barrel AR15 Upper Assembly with 10" Rail and Micro Slim Cone Flash Can

The 300 AAC Blackout was designed to achieve energies like the 7.62x39 Soviet in an AR16 while using standard AR15 magazines at their full capacity. The 7.62 Soviet's cartridge taper prevented reliable feeding in AR magazines and created wear on the bolt. From the 14.5in barrel of the AR15, the 556 round has an effective point target range of 500 yards. The bullet has significant drop, drift, and energy loss at that distance. From a 16in barrel, a 125gr 300 BLK round has a lower velocity and similar bullet drop and drift at shorter distances. However, it has the same amount of energy at 700 yards that the 556 has at 500 yards. In terms of hit probability, the Blackout has an effective range of 450 yards. From a 9in barrel, the 125 gr BLK round has the same muzzle energy as the 556 from a AR15, and 5 percent more energy at 440 yards. In comparison with 7.62×39mm rounds, 300 BLK rounds with varying loads have a better ballistics and more energy out of similar length barrels.

    Amazing customer service. Order a upper. Had a small issue, handled is with ease and sent out a new upper while still returning old one. Still waiting for refund but I’m sure they’re good for it.

    10.5" 300blk Upper

    Overall very happy with ordering this product. Excellent customer service. Quick email replies. I even spoke over the phone with the owner. He sent pictures of what my upper looked like. Easy purchase and overall happy! I have not shot the upper yet. From what I see and feel it is of great quality. I requested a parts list since they use a variety of barrels etc. I have not received it yet. I look forward to shooting it.
