12.7 mm AAMG Quiz

The receiver is the central part of the machine gun. It holds the barrel assembly, bolt assembly, and trigger mechanism, allowing for the smooth operation of the gun and ensuring it locks properly.

The bolt assembly is responsible for the entire firing cycle. It includes loading, locking, firing, extracting, and ejecting the cartridge.

The feed mechanism ensures continuous firing by moving cartridges to the feeding position for automatic firing.

The trigger mechanism works hand in hand with the bolt assembly to fire the machine gun. It initiates the entire firing sequence.

The gun mount serves as the weapon's foundation. It holds the gun in position while allowing it to aim within its limited range.

The locking mechanism prevents the gun from moving out of position while elevation and traverse adjustments are made.

The fine sighting mechanism helps the gunner aim accurately using the ground sight. It allows for precise adjustment in both elevation and traverse.

The loading mechanism brings the first cartridge into position for firing. This process occurs when the user pulls the bolt slide frame back, unlocking the bolt and feeding the first cartridge into the feed slot.

The process of taking apart the machine gun for cleaning, lubrication, inspection, and correcting malfunctions.

The first step in disassembling a machine gun is to remove the back plate group.

To remove the back plate group, you need to fix the gun body in a level position, unscrew the trunnion locking nuts, clear the piston tube, and pull out the connecting bolt.

To remove the trigger mechanism frame, hold the connecting lugs on the frame, press the rear-end of the receiver, and pull the frame out rearward.

The process of taking apart the feed mechanism involves removing the split pin, nut, connecting bolt, and then separating different parts of the mechanism.

The bolt assembly is removed by pressing down the rear part of the receiver, pulling the cocking handle backward, and then gently removing the assembly.

After removing the bolt assembly, you can separate the bolt body from the bolt slide and then remove the extractor and firing pin.

The final step in disassembling the bolt assembly is to remove the return spring and piston.

The process of taking apart the gun for maintenance or repair.

The process of putting the gun back together after disassembly.

A safety feature that prevents the gas regulator from accidentally detaching.

A component that regulates the amount of gas used to cycle the bolt. It helps to control the firing rate.

A part of the bolt assembly that holds the barrel securely in place.

A part of the bolt assembly that extracts spent cartridges from the chamber.

A part of the bolt assembly that ignites the primer in the cartridge, starting the firing cycle.

A component of the feed mechanism that pushes cartridges into the chamber for firing.

The process of inserting a linked belt of ammunition into the feed mechanism of a machine gun, ensuring the first round is ready for firing.

The mechanical action of the loading handle being pulled back, causing the bolt slide to move backward, unlocking the bolt and preparing the next round for firing.

The part of the machine gun that holds the linked belt of ammunition, ensuring a smooth and efficient supply of rounds during firing.

When the bolt assembly is in its front position, the locking mechanism ensures the gun is securely locked while the piston is ready to operate within the gas regulator.

The part of the machine gun that holds the belt while the first round is being fed into the feeding mechanism.

The part of the bolt slide that is engaged by the loading handle, driving the bolt slide backward and initiating the firing cycle.

The process of supplying a new cartridge to the chamber for firing.

The spring that is stretched when the bolt assembly is in its front position, providing the energy for the bolt to cycle back and forth.

The area where the machine gun is placed must have a clear view of the surrounding area to allow for firing at approaching aircraft from all directions.

The lowest angle the gun barrel can be lowered, critical for defending against aircraft flying low to the ground.

The position where the AAMG is placed should be relatively flat and stable to ensure smooth firing.

The site should offer natural concealment from enemy observation to protect the gun and crew.

The site needs to be suitable for effective wireless communication if the AAMG is equipped with a radio.

The AAMG position should be beneficial for defending against ground attacks, as well as air attacks.

The number of available weapons can limit the amount of defensive firepower deployed.

The maximum range at which the 12.7mm AAMG can effectively engage targets.

The rearward movement of the bolt slide forces the firing pin back along with its housing.

When the bolt slide moves backward, the camming shoulders on the firing pin are released from the locks.

The shaped groove guides the camming shoulders on the firing pin as they retract, ensuring they leave the locking recesses.

The return spring helps the bolt slide move backward by creating resistance.

The rearward movement of the bolt slide causes the long feed arm to move backward, which then forces the feed slide to move rightward.

A feed pawl is a component of the feed mechanism that positions the first round for firing while the belt holding pawl keeps the second round in reserve.

As the bolt slide passes over the sear, the sear spring stretches and pushes the sear up, locking the sear groove and keeping the bolt assembly in the rear position.

Pulling the trigger disengages the sear, allowing the bolt slide to move forward under the force of the return spring.
