Ice can build up on the breech and stop moving parts
in their tracks. Keep those parts free of moisture.

The gun tube needs more frequent cleaning
during cold weather because of residue left
from incomplete burning of propellant charges.

CLP can be used as an alternative to bore
cleaner and is effective down to -10°F. NSN 9150-
01-054-6453 gets a 1-pt bottle of CLP with a
trigger sprayer. A gallon comes with NSN 9150-
01-053-6688.
For colder temperatures, LAW is preferred for
cleaning. A 1-qt bottle comes with NSN 9150-00-
292-9689.

You’ll find more cold weather info in FM 9-207,
Operations and Maintenance of
Ordnance Material in Cold Weather:
You’ll need your AKO login and password to access the FM online.
