8" 300 BLACKOUT Faxon Nitride Mid-Weight Barrel AR15 Upper Assembly with 7" Gen 1 Quad Rail and A2 Flash Hider

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.

    AR15 Pistol Build

    My 1st transaction with AR15parts.com and for sure will not be the last. Bought the 300 Blackout 8" Faxon with 7" handguard and the complete pistol lower. I had the pleasure of dealing with both Stephen and Alan. These guys were fantastic and the weapon received is perfect. It's like getting a custom made AR given the vast selection of components. And the price was awesome. Best bang for the buck. Thanks to all involved. PS Please send ammo...
