NRA NRA Firearm Inspection & Testing

Question 1

What is the first step a gunsmith should perform when receiving a firearm for service?

Accepted Answer

Visually and physically inspect it to confirm it is unloaded and safe before handling

Answer

Before any work is done, the gunsmith must verify the firearm is completely unloaded and safe to handle, preventing accidental discharge during inspection.

Question 2

What is a function check and when should it be performed?

Accepted Answer

A systematic test of the firearm's mechanical functions after service to verify proper operation before return to the customer

Answer

A function check is a series of hands-on tests verifying that the safety, trigger, feeding, and other mechanical functions operate correctly after repairs or maintenance.

Question 3

What does inspecting a firearm for 'timing' mean, particularly in a revolver?

Accepted Answer

Verifying that the cylinder indexes and locks in alignment with the bore as the hammer is cocked

Answer

Revolver timing inspection verifies that the cylinder indexes fully into alignment with the barrel bore as the hammer reaches full cock, ensuring safe and accurate firing.

Question 4

What does a 'go gauge' verify during a headspace check?

Accepted Answer

That the bolt will close fully on the minimum acceptable headspace dimension

Answer

A GO gauge represents the minimum acceptable headspace; if the bolt closes fully on the GO gauge, the headspace is not too tight for safe functioning.

Question 5

What condition is indicated when a firearm fails to close on the NO-GO headspace gauge?

Accepted Answer

The headspace is within safe specifications

Answer

If the bolt does not close on the NO-GO gauge, the headspace is within the safe range between minimum and maximum, indicating an acceptable chamber.
