Maintenance Protocols Flashcards

Before beginning any cleaning session, what should an instructor require students to do with all live ammunition?

Answer: Remove it from the cleaning area entirely

NRA guidance is to keep ammunition out of the cleaning area so a live round cannot be accidentally chambered.

When possible, from which end should a rifle bore be cleaned to protect the muzzle crown?

Answer: The breech (chamber) end

Cleaning from the breech prevents rod contact from damaging the crown, which directly affects accuracy.

What is the primary purpose of a bore guide when cleaning a bolt-action rifle?

Answer: To center the rod and keep solvent out of the action

A bore guide aligns the rod with the bore and keeps solvent from running into the trigger group and action.

A student pushes a bronze brush halfway into the bore and then reverses direction. What is the main concern?

Answer: Reversing inside the bore can bend bristles and damage the rod or bore

Brushes should be pushed fully through before being withdrawn, because reversing mid-bore stresses bristles and the rod.

Why should lubricant be applied sparingly to most firearm moving parts?

Answer: Excess oil attracts dirt, unburned powder, and grit

A thin film protects parts while excess oil collects debris that can cause malfunctions.

Which document should be consulted first for the correct disassembly procedure of a specific firearm?

Answer: The manufacturer's owner's manual

Each firearm's disassembly differs, and the owner's manual gives the manufacturer-approved procedure.

After cleaning, what is the last step before storing the firearm?

Answer: Check again that it is unloaded and wipe off excess oil

A final unloaded check and removal of excess oil or solvent ensure safe storage and prevent residue buildup.
