Advanced Armament Corp's 300 AAC BLACKOUT (7.62x35mm) upper for the M4, HK-415, AR-15 and M16 platform cycles full auto with both 300 BLK subsonic and supersonic ammo within normal operating specitications with no user adjustments required. Full power 115-125 grain ammunition matches the ballistics of the 7.62x39mm AK, and eclipses 5.56mm with much higher-mass projectiles for a more dramatic effect on the target, Or choose subsonic cartridges for optimal use with a sound suppressor - 220 grain Sierra OTM (open-tip match) bullets vastly outperforms a 9mm MP5-SD in penetration and long range accuracy. At 300 meters, 300 BLK has 16.7% more energy than 7.62x39mm. Max effective range, using M4 military standards for hit probability is 460 meters for a 16 inch barrel. A Knight's Armament free-floating URX helps maintain accuracy while providing for the mounting accessories. The bolt carrier group meets full-auto specifications (full auto operation requires a full-auto lower receiver). The bolt uses Carpenter 158 steel. The gas-key is heat-treated and properly staked. Further, the carrier is internally chrome-lined. The 1/8 twist barrel is 16 inches. Full-auto chamber dimensions enhance feeding and extraction compared to a match chamber. Finally, the barrel, including bore and chamber, is nitrided to provide extreme corrosion resistance and high hardness for a long life. The muzzle is threaded 5/8-24 and includes an AAC 51-tooth BLACKOUT flash suppressor.
