What is the role of a 'bore snake' as an alternative cleaning tool?
Answer: A one-pass cleaning cord that combines a bronze brush and cleaning floss in a single pull-through tool
A bore snake is a quick-cleaning tool that combines a weighted pull cord, bronze brush, and floss sections so the bore can be cleaned in a single pass without a rod.
What does inspecting the rifling during barrel cleaning help a GSI instructor identify?
Answer: Signs of excessive wear, erosion, or obstructions that could affect accuracy or safety
Inspecting the rifling allows detection of unusual wear, bulges, pitting, or obstructions that might indicate a safety concern or reduction in the firearm's accuracy.
Why is it important to remove all solvent from the barrel and action before applying lubricant?
Answer: Residual solvent can dilute and break down the lubricant, reducing its protective effectiveness
Solvents are designed to dissolve fouling and will also degrade lubricating oils if mixed, so all solvent must be wiped out before a fresh application of lubricant is applied.
What firearm component should a GSI instructor emphasize cleaning regularly to prevent misfires?
Answer: The firing pin and firing pin channel
A dirty or obstructed firing pin channel can slow or block the firing pin's movement, resulting in light primer strikes and misfires.
What is the danger of over-lubricating a firearm?
Answer: Excess oil can migrate to the ammunition, deactivating primers and causing misfires
Excess lubricant can work its way into cartridges and primer pockets, deactivating the sensitive primer compound and causing unreliable ignition or misfires.
How should a GSI instructor recommend storing a cleaned, lubricated firearm long-term?
Answer: In a secure gun safe or lock box in a cool, dry environment, unloaded and with a light protective coat of oil
Long-term storage in a secure, cool, dry location with a light coat of protective oil prevents corrosion while keeping the firearm safe, accessible, and ready for use.
