Mechanisms and Components
The Thompson T850 Submachine Gun showcases a robust design that integrates various components to achieve its impressive performance. At the heart of the machine gun lies its intricate internal mechanisms and components, which are crucial for understanding its operation.
The T850’s internal mechanisms are characterized by a combination of steel and aluminum alloy components, providing a perfect balance between strength and durability. The machine gun’s bolt carrier is a key component, featuring a steel alloy design that houses the recoil spring assembly, the firing pin, and the extractor.
Internal Components
The bolt carrier is attached to the barrel assembly, and its movement is guided by a set of steel rails, which maintain precise alignment and control. The recoil spring, housed within the bolt carrier, provides the necessary force to cycle the action after each shot, returning the bolt to its forward position.
As the bolt moves rearward, it strikes the recoil spring, compressing it, and then returns forward, driven by the spring’s stored energy. This process is critical in maintaining a high rate of fire. Furthermore, the bolt carrier features a set of serrations, allowing for secure attachment to the barrel assembly.
Bolt Carrier Group (BCG)
The bolt carrier group (BCG) is a critical component, consisting of the bolt carrier, the firing pin, and the extractor. The BCG is engineered to withstand the intense forces generated by each shot. When a round is fired, the bolt carrier moves rearward, striking the firing pin, which in turn ignites the primer.
The extractor plays a vital role in removing spent cases from the chamber, allowing for proper operation of the machine gun. The BCG’s design ensures smooth and efficient operation, with precise alignment of components to maintain accuracy.
Barrel Assembly
The barrel assembly features a steel alloy design, with a chrome-lined bore to withstand the rigors of high-velocity ammunition. The barrel is attached to the bolt carrier via a set of steel rails, providing precise alignment and control.
The barrel is designed to dissipate heat efficiently, with a series of cooling slots and a heat sink to prevent overheating. This allows for sustained fire over extended periods.
Receiver and Stock
The receiver is constructed from steel alloy, housing the internal mechanisms and components, including the bolt carrier and barrel assembly. The receiver features a set of rails, providing a secure attachment point for the stock assembly.
The stock assembly is designed to provide a stable shooting platform, with a adjustable shoulder pad and a set of cheek weld points for comfortable positioning. The stock assembly is engineered to withstand the recoil forces generated by the machine gun, ensuring controlled and accurate operation.
Trigger Assembly
The trigger assembly consists of a steel alloy design, with a set of components that work in concert to provide a smooth and responsive trigger pull. The trigger features a set of serrations, allowing for secure attachment to the receiver.
The trigger assembly is designed to withstand the intense forces generated by repeated firing, with a set of components that maintain precise alignment and control. This ensures reliable and consistent operation of the machine gun.
Magazine and Feeding System
The magazine is designed to hold a standard capacity of ammunition, featuring a steel alloy design with a set of rails to attach to the receiver. The feeding system is engineered to ensure smooth and reliable feeding, with a set of components that work in concert to maintain precise alignment and control.
The magazine features a set of lips, allowing for secure attachment to the receiver, and a set of ribs, providing a secure hold on the ammunition. The feeding system consists of a set of steel components, including the follower, the spring, and the catch, working in concert to maintain precise alignment and control.
Firepower and Range

The T850 submachine gun is renowned for its exceptional firepower, making it a formidable tool on the battlefield. This firepower is attributed to several factors, including its ability to chamber a high volume of ammunition and its efficient firing mechanism.
Comparison with Other Submachine Guns, T 850 with machine gun
When compared to other submachine guns on the market, the T850’s firepower stands out as one of the most impressive. In terms of rate of fire, the T850 can discharge over 800 rounds per minute, significantly outpacing many of its contemporaries.
| Submachine Gun | Rate of Fire (Rounds per Minute) |
|---|---|
| Uzi | 600-650 |
| MP5 | 600-650 |
| T850 | 800-900 |
This exceptional rate of fire, combined with the T850’s large magazine capacity, makes it a force to be reckoned with in close-quarters combat scenarios.
Types of Ammunition Used
The T850 is capable of chambering a variety of ammunition types, each with its unique effects. The most common type of ammunition used with the T850 is the 9x19mm Parabellum round, which is well suited for close-quarters combat due to its relatively low penetration depth and high stopping power.
- The 9x19mm Parabellum round is designed to penetrate soft targets, such as flesh and fabric, while minimizing penetration of harder materials, such as bone.
- It is also effective at stopping targets due to the relatively high kinetic energy imparted to the target upon impact.
In addition to the 9x19mm Parabellum round, the T850 can also chamber higher-velocity rounds, such as the 10mm Auto, which offer increased penetration depth at the expense of reduced stopping power.
Maximum Effective Range
The maximum effective range of the T850 is approximately 150-200 yards (137-183 meters), depending on the type of ammunition used and the environmental conditions present on the battlefield.
The T850’s maximum effective range is limited by the relatively low muzzle velocity of the 9x19mm Parabellum round, combined with the effects of wind and atmospheric drag.
This range can be extended to some extent through the use of specialized ammunition, such as the 10mm Auto, which offers increased penetration depth at the expense of reduced accuracy.
