Q & A
What happens when the chamber is empty and there is pressure?
-When the chamber is empty, the pressure causes the diassembly of the firearm, which is a safety mechanism to prevent accidents.
What is the significance of the working surface of a bolt lug being of a gelikoid figure?
-The gelikoid figure of the working surface of a bolt lug provides a unique shape that can enhance the locking mechanism, ensuring a secure fit when the bolt is in place.
What is the purpose of lens distortion correction in the context of a firearm?
-While lens distortion correction is typically associated with optics, in this context, it could refer to the alignment or adjustment of sights to account for any distortion that might affect accuracy.
How does the bolt carrier move the cartridge into the chamber?
-The bolt carrier moves forward, utilizing a small plane within the multi-faceted groove, which pushes the bolt and the cartridge into the chamber.
What is indicated by the hatching on the diagrams?
-The hatching on the diagrams represents different planes and mechanisms, such as the plane that moves the bolt forward and the slantways planes that initiate bolt rotation.
What causes the bolt to rotate during the forward movement?
-The interaction of two slantways planes at the end of the forward movement of the bolt causes it to rotate, preparing it for the locking position.
What happens when the bolt carrier moves forward after the bolt has rotated?
-The bolt carrier's forward movement, along with the rotation indicated by the slantways plane, causes the bolt to close, locking it in place for firing.
How does the bolt get blocked in the closed position?
-The bolt is blocked in the closed position by the plane of the multi-faceted groove of the bolt carrier, which is indicated by hatching.
What is the function of the red lines in the diagrams?
-The red lines in the diagrams are visual aids to help trace the movement of the bolt carrier and the bolt throughout the firing cycle.
How does the bolt open when the bolt carrier moves backward?
-When the bolt carrier moves backward, another pair of slantways planes in the multi-faceted groove interacts, causing the bolt to turn and open.
What are the two main types of Soviet-made magazines mentioned in the script?
-The two main types of Soviet-made magazines mentioned are steel and bakelite, which differ in material and possibly in durability and weight.
What is the role of the Auto Sear in the firing process?
-The Auto Sear is a mechanism that allows for automatic shooting when the green detail is active. When switched to automatic mode, the green detail is blocked, enabling continuous firing.
What does the retarder do in terms of the firing rate?
-The retarder, indicated by the blue part, slows down the firing rate, providing a control mechanism to regulate the speed of automatic fire.
How does the lock mechanism work in the context of the bolt?
-The lock mechanism is activated when the retarder is engaged, which then blocks the bolt, preventing further movement and preparing it for reloading or safe storage.
What is the purpose of rear sight adjustment?
-Rear sight adjustment allows the shooter to align the sights for accurate aiming, compensating for distance and other factors that may affect the trajectory of the bullet.
Outlines
π§ Bolt Carrier and Cartridge Chambering Mechanism
This paragraph describes the intricate process of a firearm's bolt carrier and cartridge chambering. It explains how the bolt carrier moves forward under pressure, utilizing a multi-faceted groove with a specific working surface to advance the cartridge into the chamber. The text also details the role of a small plane within this groove, indicated by hatching, which is crucial for initiating bolt rotation and ensuring the bolt's closure. The red lines serve as visual aids to trace the movement of the bolt carrier and the bolt. Additionally, the paragraph discusses the synchronization of the bolt and bolt carrier movement and the function of the bolt as a lever for easier extraction of expended casings. It also mentions two main types of Soviet-made magazines: steel and bakelite, and touches upon the Auto Sear mechanism.
π― Firing Mechanism and Adjustments
The second paragraph focuses on the firing mechanism of a firearm, detailing the transition from a single shot to an automatic shooting mode. It highlights the 'green detail' which becomes active during single shot firing and is blocked during automatic mode. The paragraph also explains the function of the retarder, depicted in blue, which slows down the firing rate and activates the lock to prevent the bolt from moving. Furthermore, it describes the rear sight adjustment feature, allowing forηε accuracy. This section provides a comprehensive overview of the firearm's firing process and the adjustments available to the shooter for different shooting scenarios.
