NRA Maintenance Protocols 2

Question 1

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

Accepted Answer

Remove it from the cleaning area entirely

Answer

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

Question 2

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

Accepted Answer

The breech (chamber) end

Answer

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

Question 3

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

Accepted Answer

To center the rod and keep solvent out of the action

Answer

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

Question 4

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

Accepted Answer

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

Answer

Brushes should be pushed fully through before being withdrawn, because reversing mid-bore stresses bristles and the rod.

Question 5

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

Accepted Answer

Excess oil attracts dirt, unburned powder, and grit

Answer

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