.300 AAC Blackout delivers better ballistic performance than both standard-velocity 5.56 loads and subsonic 9mm loads, making it the ideal choice for an AR pistol. If you'd like to get started on your very own .300 AAC Blackout AR pistol, look no further. This Complete Upper from Anderson comes with a 7.5" barrel and a very nice M-LOK handguard.
Anderson makes almost all components in-house, so they can control quality like few others while still delivering exceptional value. Don't start with any other upper.
PLEASE NOTE: Bolt carrier group and charging handle not included.
