The INSAS (Indian Small Arms System) rifle is an Indian-made assault rifle. It stands for "Indian National Small Arms System." The rifle has several components, including:


  • Receiver: The main body of the rifle that houses the firing mechanism and other internal components.
  • Barrel: The long tube through which the bullet travels when fired.
  • Bolt Assembly: The bolt assembly includes the bolt carrier, bolt itself, and firing pin. It is responsible for chambering rounds, firing, extracting spent casings, and ejecting them.
  • Handguard: The part of the rifle that surrounds the barrel and protects the shooter's hand from getting burned by the hot barrel during extended firing.
  • Gas System: The mechanism responsible for diverting some of the gas produced by the fired round to cycle the rifle's action. This is a common feature in many modern automatic rifles.
  • Stock: The rear part of the rifle that the shooter holds against the shoulder. It typically contains the rifle's recoil-absorbing components and might also house the rifle's magazine.
  • Pistol Grip: The grip located beneath the receiver, which the shooter's hand holds onto. It allows for better control and handling of the rifle.
  • Magazine: The detachable container that holds and feeds ammunition into the rifle's chamber.
  • Trigger Assembly: The components responsible for releasing the firing pin and firing the weapon when the trigger is pulled.
  • Sights: The rifle's sights, which might include iron sights for aiming or potentially optical sights for better targeting.
  • Muzzle Brake/Flash Hider: A device attached to the muzzle of the rifle to reduce recoil and muzzle rise, as well as to minimize the flash generated by firing.
  • Butt Plate/Pad: The part of the stock that rests against the shooter's shoulder. It helps to absorb recoil and provides comfort while firing.
  • Selector Switch: If the rifle has select-fire capabilities (semi-automatic and automatic modes), this switch allows the shooter to choose between firing modes.


These are some of the key components of the INSAS rifle. Keep in mind that the specific design and features might vary based on the model and variant of the rifle.
