.300 AAC Blackout is a highly versatile round that delivers better energy and penetration at engagement ranges than 5.56 while also functioning more reliably with a suppressor. If you want to built a subsonic .300 AAC Blackout AR, this is the Upper you want.
It comes with a pistol-length gas system that cycles reliably with lower-pressure subsonic loads, as well as a 16" barrel and effective Knight Stalker flash hider. Even better, Anderson makes almost all components in-house, so they can control quality like few others while still delivering exceptional value.
PLEASE NOTE: Bolt carrier group and charging handle not included.
