Which item is considered a firearm part?

• A. The trigger
• B. The stock
• C. The barrel
• D. The slide, bolt or breech block

Answer: (D)

Understanding which components are considered firearm parts focuses on the parts that actually enable the gun to fire. The slide, bolt, or breech block are core moving pieces of the firearm’s action. They chamber a round, seal the breech, extract spent cases, and prepare the next round for firing. These elements are integral to the firing mechanism itself, so they’re classified as firearm parts in this context. The other items shown—such as the stock, which is mainly a handle and support, and the barrel, which directs the projectile—are important components but aren’t identified here as the parts that constitute the firearm’s firing action. The trigger is part of the firing mechanism too, but in this particular framing the slide, bolt, or breech block best fits the definition of a firearm part being tested.
