CFA Condition Assessment & Functional Evaluation 3 — Questions and Answers
Question 1: Muzzle erosion in a rifle barrel is most accurately assessed using:
- A chamber pressure gauge
- A muzzle crown gauge or bore scope to measure erosion depth and concentricity (Correct answer)
- A field strip inspection only
- A visual inspection from the breach end only
Correct answer: A muzzle crown gauge or bore scope to measure erosion depth and concentricity
A muzzle crown gauge or bore scope reveals the degree of erosion, pitting, or asymmetry at the muzzle that would impact accuracy and value.
Question 2: A firearm described as 'mechanically excellent but cosmetically poor' would typically fall into which NRA category?
- Perfect
- Good (Correct answer)
- Fair
- Poor
Correct answer: Good
NRA 'Good' grade applies to firearms that function reliably but show significant wear or finish loss on exterior surfaces.
Question 3: When evaluating a semi-automatic pistol's extractor, which condition most directly compromises extraction reliability?
- Surface bluing loss on the extractor
- A worn or broken extractor hook that cannot tension against the cartridge rim (Correct answer)
- Extractor that is slightly oversized
- An extractor with minor tool marks from factory fitting
Correct answer: A worn or broken extractor hook that cannot tension against the cartridge rim
The extractor hook must maintain firm tension on the cartridge rim; a worn or broken hook leads to failures to extract, a critical functional defect.
Question 4: A firearm appraiser notes 'freckling' on a blued steel receiver. This term refers to:
- A decorative pattern applied by the factory
- Tiny scattered rust spots that have begun to pit the bluing surface (Correct answer)
- Tool marks left during the machining process
- Carbon fouling deposits from firing
Correct answer: Tiny scattered rust spots that have begun to pit the bluing surface
Freckling describes the early stage of surface rust appearing as small scattered spots that compromise bluing and begin pitting the steel.
Question 5: The head space in a bolt-action rifle is best described as:
- The clearance between the bullet and the rifling
- The distance from the bolt face to the datum line of the chamber (Correct answer)
- The space between the stock and the action
- The gap between the trigger and the sear
Correct answer: The distance from the bolt face to the datum line of the chamber
Headspace is the critical dimension from the bolt face to the chamber's datum line; excessive headspace is dangerous and causes case separation.
Question 6: Which condition would cause an appraiser to classify a double-barrel shotgun as 'non-functional'?
- A loose rib with minor lifting at the muzzle end
- Action that does not lock up and cannot be safely closed for firing (Correct answer)
- A replaced buttpad that differs from original
- Minor case color fading on the receiver
Correct answer: Action that does not lock up and cannot be safely closed for firing
An action that cannot lock closed makes firing impossible and dangerous, rendering the firearm non-functional regardless of other attributes.
Question 7: When assessing the bore of a .22 LR rimfire rifle, an appraiser notices significant lead fouling buildup. The recommended first step for accurate bore condition assessment is:
- Immediately grade the bore as 'Poor' due to fouling
- Clean the bore thoroughly before conducting the condition assessment (Correct answer)
- Assess through the fouling since cleaning may mask wear
- Replace the barrel before completing the appraisal
Correct answer: Clean the bore thoroughly before conducting the condition assessment
Lead fouling must be removed before bore assessment, as it masks the true rifling condition, wear depth, and any pitting beneath it.
