Which component is cited as the primary part to remove to disable a weapon?

• A. Stock
• B. Bolt carrier group
• C. Charging handle
• D. Receiver

Answer: (B)

The main concept here is understanding which part controls the actual firing cycle of a rifle. The bolt carrier group is the core moving assembly that drives chambering a round, locking the bolt, extracting and ejecting spent cases, and returning the bolt to battery for the next cycle. In most platforms, gas pressure powers this group to cycle automatically after each shot. If you remove or disable the bolt carrier group, the action can’t cycle at all, so a round can’t be chambered or ejected and the weapon can’t function. Other parts like the stock, charging handle, or receiver affect handling or housing but don’t stop the internal cycling mechanism from operating in the same way. So, removing the bolt carrier group is the most direct way to render the weapon nonfunctional because it eliminates the essential firing cycle.
