In most cases, should the extractor be removed during a headspace test?

• A. YES
• B. NO
• C. Sometimes
• D. Always

Answer: (A)

The key idea is that headspace measurements must be taken with the chamber unobstructed so the gauge seats correctly. The extractor is a moving part that can intrude into the chamber area or push against the gauge, which can prevent the gauge from seating at the proper depth. When the extractor is removed, there’s no interference, allowing the go/no-go gauges to sit fully against the chamber shoulder and give an accurate reading. This leads to reliable results and helps ensure safety by not masking an improper headspace. Always verify the firearm is unloaded and follow safe disassembly procedures before testing.
