MAINTENANCE IN
EXTREME WEATHER
EXTREME COLD: Clean and lubricate Rifle in a warm
room with Rifle at room temperature. Do not lay a warm
Rifle directly on snow or ice. Moving Rifle from cold into
warmth will cause condensation which could keep Rifle
from functioning.
HOT, WET CLIMATES: Clean and lube Rifle more
frequently in moist climates. Inspect hidden surfaces
of Bolt and Carrier Assembly, Upper Receiver, and
Chamber / Barrel Extension (Locking Lugs), and Lower
Receiver and Receiver Extension Assembly (Buffer
Tube) for rust or corrosion. Also pay close attention to
the Spring Loaded Detents on the rifle. Wipe off any
hand / finger prints on the Rifle as they can accelerate
the onset of rust or corrosion.
RAINS: DO NOT FIRE THE RIFLE IF WATER IS PRESENT
IN THE BARREL. ALWAYS drain any water from Barrel
prior to firing. Dry the Bore with a Swab and Cleaning
Rod if wet.
COMPONENT VARIATIONS
This manual is intended to instruct the AAC Rifle
Operator in all necessary aspects of Maintenance,
Disassembly, Reassembly, Operation and
Troubleshooting of any AR15-style AAC Rifle. Within
the AAC Weapon System family, there can be infinite
variations of Barrel Length, Stock Type, Receiver,
Forend and Sights. The rifle you own, or are using,
may vary in appearance from the photographs
and illustrations in this Manual, but the concepts,
procedures and practices recommended in this Manual
are universal to the AAC AR15-style weapon family.
300 AAC BLACKOUT PDW UPPER
The 300 AAC BLACKOUT (300 BLK) cartridge is highly
efcient and in most cases outperforms 5.56mm with
less powder and resulting blast. The included AAC
BLACKOUT flash suppressor eliminates all secondary
muzzle flash. These properties make it ideal for
personal security.
