4.2 Maintenance Procedures for Adverse Climate Conditions
1. When operating in adverse environments LWRC Inc. recommends utilizing shoot
through muzzle covers and gun covers (if tactical situation permits).
2. Pay particular attention that the ejection port cover is closed at all times when not
firing your weapon. If weapons must be grounded stuff a rag into the magazine
well.
3. In blowing sand or snow conditions conduct frequent functions checks of your
weapon and take every opportunity to remove sand or snow from your weapon.
A small paint brush is highly recommended for this task. Blow sand from weapon
with compressed air if available.
4. Do not lubricate the interior of the upper receiver or exterior of the gas piston
components when operating under field conditions in extremely sandy or snowy
environments.
5. When performing routine maintenance remove the upper rail (hand guard on M6
model) and brush any sand or snow from the piston components.
6. Apply point lubrication as sparingly as possible.
4.3 Special Arctic Environment Considerations
1. Keep weapons at ambient outdoor temperature whenever possible and use an arctic
rated lubricant.
2. If weapons must be brought into a warm area, allow weapons to warm up to the
room temperature, detail disassemble and perform detailed maintenance. Pay
particular attention to removing all condensation from weapon before going back
into cold temperatures.
3. Even if weapons are kept outdoors, temperatures can fluctuate above and below
freezing causing condensation to develop then freeze in the weapon’s moving
components. Perform frequent functions checks to ensure weapon is operable.
4. If weapon is dropped in the snow clean it immediately. At a minimum break the
weapon down shotgun style and remove any snow from the upper receiver and bolt
carrier. Clean snow from gas piston components.
5. If your weapon does freeze shut DO NOT FIRE IT to un-jam the weapon. Warm
weapon with body heat or a camp stove (hold weapon at least eight inches above
flame and remove magazine prior to warming) until un-jammed then clean or fire
immediately.
