Maintenance Protocols Flashcards

How should an instructor demonstrate maintenance to a class with respect to muzzle direction?

Answer: Muzzle pointed in a safe direction at all times, even when unloaded

NRA's first rule applies during maintenance: always keep the gun pointed in a safe direction.

What indicates that a bore is clean when running patches through it?

Answer: Patches come out clean or nearly clean

Patches emerging clean show fouling and solvent have been removed from the bore.

Why should copper solvent not be left in a bore for extended periods unless the manufacturer allows it?

Answer: It may etch or damage the bore steel

Aggressive copper-removing solvents can harm the barrel if left longer than directed.

What should be done with used solvent-soaked patches and rags?

Answer: Dispose of them properly per label and local guidance

Solvent-soaked materials can be flammable or hazardous and should be disposed of per the product label and local rules.

Which practice helps prevent rust caused by fingerprints on blued steel?

Answer: Wiping exterior metal with a lightly oiled cloth after handling

Skin oils and salts cause rust, and a lightly oiled wipe-down removes them and protects the finish.

Why is it important to inspect the bore for obstructions after cleaning?

Answer: A leftover patch or debris can cause dangerous pressure if fired

An obstruction such as a stuck patch can cause a bulged or burst barrel when fired.

Which storage condition best reduces corrosion for long-term firearm storage?

Answer: A cool, dry location, possibly with a dehumidifier or desiccant

Low humidity and stable temperatures minimize rust, and dehumidifiers or desiccants help control moisture.
