3 basic parts to all modern firearms

• A. action, stock, barrel
• B. trigger, magazine, chamber
• C. receiver, scope, buttstock
• D. safety, grip, muzzle

Answer: (A)

Three basic parts of all modern firearms are the action, the barrel, and the stock. The action is the mechanism that handles loading, locking, firing, and extracting spent cartridge cases; it’s the engine that cycles the round from chamber to discharge. The barrel is the long tube the bullet travels through; its purpose is to guide the bullet and, if it’s rifled, to impart stability for accuracy. The stock provides the support and alignment you hold against your shoulder or forearm, helping you aim and absorb recoil.

Other components like triggers, magazines, safeties, or scopes are important, but they aren’t the core structural trio shared by all modern firearms. A firearm’s basic framework is built around the action, the barrel, and the stock.
