Failure to extract is commonly caused by which conditions?

• A. Failure to extract casing, split case swollen in chamber, extractor hook broken/dirty
• B. Improper seating
• C. Worn sights
• D. Dirty magazine

Answer: (A)

Failure to extract happens when the spent cartridge cannot be pulled from the chamber as the firearm cycles. The extractor must grip the rim and yank the case free; if the extractor hook is broken or dirty, it can’t engage the case properly, so the case stays stuck. A swollen or split case in the chamber also creates a tight fit or snag, which prevents withdrawal on the next cycle. These conditions directly disrupt the extraction process, making them the most likely cause of failure to extract. Other issues listed relate to different malfunctions. Improper seating affects chambering of a new round rather than pulling a spent case out. Worn sights affect aiming, not extraction. A dirty magazine can cause feeding problems, but it doesn’t typically cause the spent case to fail to be extracted.
