Thank you for buying an AAC product. Please read the full owner’s manual before use. If you do not have one, please
call AAC to get one. This document is not a complete manual but will provide additional information to help you get the
best performance from your upper.
The 300 AAC BLACKOUT (300 BLK) cartridge is highly efcient and outperforms 5.56mm when used in a short barrel rie
and comes very close to the energy of 6.8 SPC but with less powder and resulting blast. The included AAC BLACKOUT
ash suppressor eliminates all secondary muzzle ash. Compared to subguns like the MP5-SD, it has more accuracy,
more penetration, and 165% the energy at 200 meters. These properties make it ideal for personal security.

PARTS REPLACEMENT
If you remove the gas block, reset the set-screws to 35-40 inch/lbs of torque after applying oil to the threads.
Thread-locking adhesives are not recommended because then you will not be able to remove the screws.
The replacement schedule for parts depends on the intensity of use and the intended use. After any parts
replacement, give weapons a safety/function check before use.
Always check headspace after changing a bolt, barrel, or barrel extension.
