The STEN MK2 is a British submachine gun designed in World War II as a response to the need for a simple, low-cost, and effective firearm for armed forces. Known for its iconic design and operational efficiency, the STEN MK2 became a significant player in campaigns throughout World War II and beyond. The STEN gun was developed in response to a shortage of weapons during WWII. Designed by Harold John Turpin, the gun was easily manufactured from sheet metal and required fewer precision machining tasks compared to other firearms of the era.
Key Features of the STEN MK2
- Simple Design: The STEN is famous for its straightforward and minimalist design, allowing for ease of production and repairs.
- Compact Size: The MK2’s compactness made it suitable for close-quarters combat, providing a practical solution for troops requiring mobility.
- 9mm Caliber: The STEN MK2 fired 9mm Luger cartridges, offering effective stopping power in combat.
Components of the Complete STEN MK2 Parts Kit
- Receiver: The receiver is the core component of the firearm, housing the trigger assembly and the important exposed parts necessary for function. It serves as the backbone for all other parts.
- Barrel: The STEN MK2 features a smoothbore barrel. The barrel’s length is significant for maintaining a balance between compactness and ballistic performance.
- Bolt and Bolt Carrier Group: This assembly includes the bolt, which houses the firing pin and serves to cycle the action. The bolt must fit snugly within the receiver for proper operation.
- Stock: The STEN MK2 typically features a folding stock, which enhances portability when the firearm is stowed or transported. The stock also provides stability during firing.
- Forend/Handguard: The handguard protects the user from the heat generated by the barrel during sustained fire and provides a surface for gripping.
- Trigger Assembly: This assembly includes the trigger, sear, and other essential components that enable firing. The simplicity of the trigger mechanism is characteristic of the STEN design.
- Sights: The rear and front sights are crucial for aiming. The STEN MK2’s sights are basic but effective for short-range engagements.
- Magazines: Although not always included in parts kits due to legal restrictions, the STEN typically uses 32-round magazines, which are essential for operation.
- Safety Selector: The safety selector component enables the operator to switch between safe and firing modes, contributing to user safety.
- Muzzle Device: The muzzle device may include a suppressor or flash hider, depending on the configuration and intended use of the firearm.
Assembly Considerations
Assembling a STEN MK2 from a parts kit requires knowledge of firearm assembly and compliance with local laws regarding firearm construction.
Tools Required
Essential tools for assembly include:
- Gunsmithing tool set
- Bench vise
- Riveting tools, if necessary
- Headspace gauges for checking safety and functionality
Performance and Maintenance
Once assembled, the STEN MK2 is known for its reliability and ease of use. Its low-maintenance design has made it a popular choice among collectors and enthusiasts.
Cleaning
Regular cleaning is essential to maintain performance and prevent malfunctions. The open design of the STEN allows for relatively easy access to all components for proper cleaning.
Inspection
Periodic inspections of critical components like the bolt, barrel, and magazine feed mechanisms can help identify signs of wear and ensure reliable operation.
Lubrication
Proper lubrication of moving parts, particularly the bolt and carrier, helps minimize friction and increases the lifespan of the firearm. Using the right lubricants is key to maintaining functionality, especially in high-use situations.
