GSI GSI Firearm Cleaning & Maintenance 3

Question 1

What is the role of a 'bore snake' as an alternative cleaning tool?

Accepted Answer

A one-pass cleaning cord that combines a bronze brush and cleaning floss in a single pull-through tool

Answer

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.

Question 2

What does inspecting the rifling during barrel cleaning help a GSI instructor identify?

Accepted Answer

Signs of excessive wear, erosion, or obstructions that could affect accuracy or safety

Answer

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.

Question 3

Why is it important to remove all solvent from the barrel and action before applying lubricant?

Accepted Answer

Residual solvent can dilute and break down the lubricant, reducing its protective effectiveness

Answer

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.

Question 4

What firearm component should a GSI instructor emphasize cleaning regularly to prevent misfires?

Accepted Answer

The firing pin and firing pin channel

Answer

A dirty or obstructed firing pin channel can slow or block the firing pin's movement, resulting in light primer strikes and misfires.

Question 5

What is the danger of over-lubricating a firearm?

Accepted Answer

Excess oil can migrate to the ammunition, deactivating primers and causing misfires

Answer

Excess lubricant can work its way into cartridges and primer pockets, deactivating the sensitive primer compound and causing unreliable ignition or misfires.
