So, are WASR trunnions cast or forged? Let’s take a closer look.
What are Trunnions?
Trunnions are essential components of firearms, particularly in the construction of rifles. These are the small components that are located towards the front and back of the receiver, which serve as the mounting points for the barrels. The trunnions are attached to the gun’s receiver and act as supports for the barrel. They allow the shooter to adjust the position of the barrel, making it possible to aim and fire the gun with more precision. The trunnions play an essential role in the accuracy and stability of the firearm.
The Role of Trunnions in Firearm Manufacturing
When it comes to the construction of firearms, trunnions play a crucial role in ensuring their safety and reliability. Trunnions are the components responsible for connecting the barrel to the action, which is the part of the firearm that contains the trigger, bolt, and firing mechanism. In simple terms, the trunnion is the interface between the barrel and the receiver that houses the action.
Why are Trunnions Important?
- Strength and Durability: Trunnions are subjected to tremendous forces when a firearm is fired, making it essential that they are constructed from materials that can withstand these stresses. This means that trunnions must be made from high-strength materials such as steel, titanium, or other tough alloys that can provide the required resistance to recoil and other stresses.
- Affixment of Barrel and Action: Trunnions play a critical role in holding the barrel and action securely in place during firing, so a failure or malfunction could have catastrophic consequences. The process of attaching the barrel to the action requires precise machining and fitting, as subpar or inferior quality trunnions may compromise the alignment of the barrel, which can lead to poor accuracy and performance.
- Influence on Recoil and Accuracy: The trunnion’s strength, alignment, and fit can directly impact the firing behaviour of the firearm, meaning that a poorly constructed or damaged trunnion may result in erratic behaviour during firing. As a result, trunnions are made from materials and processes that ensure maximum stability and accuracy.
Trunnion Forging Process
To produce a trunnion that can meet the high demands of firearm manufacturing, it is often produced by forging. Forging allows a trunnion to be formed under high pressure, resulting in a dense, homogenous material that possesses higher strength and durability compared to casting or other forming processes. Additionally, the forging process provides greater assurance of quality and consistency compared to other manufacturing methods, making it a favoured choice of material production for firearm trunnions.
| Forging Process Pros | Forging Process Cons |
|---|---|

Overall, trunnions play a critical role in ensuring the safety and functionality of firearms. From material selection to the manufacturing process, several factors must be considered to produce trunnions that can meet the strict demands of the firearm industry.
Forging vs. Casting Trunnions: Which is Better?
When it comes to the manufacturing of firearm parts, the two most popular methods are forging and casting. Both methods have their advantages and disadvantages, so let’s take a closer look at them to determine which is better for producing trunnions for the WASR.
- Forging: Forging involves shaping material using localized compressive forces. This method produces parts that are strong, durable, and have a good grain structure. The grain structure of a forged part is aligned with its shape, making it less prone to cracking or breaking under stress. Forging trunnions for the WASR involves heating metal and striking it with a hammer using a die or tool that has the desired shape. This process results in a finished part that is close to its final shape, requiring minimal machining or finishing. Forging is a more expensive method than casting, but its higher quality and strength make it ideal for critical parts like trunnions.
- Casting: Casting is the process of pouring molten material into a mold and allowing it to cool and solidify. This method is ideal for mass production of parts with complex shapes and designs. Casting trunnions for the WASR involves pouring molten metal into a mold with the desired shape, and then machining and finishing the resulting part to its final shape and size. Casting can produce parts that are cheaper and faster to make than forging, but the parts may have flaws like porosity and uneven grain structure that can compromise their strength and durability.
- Which is better for trunnions? While both methods have their merits, forging is considered by many to be the superior method for producing trunnions for the WASR. Forged trunnions have a more uniform grain structure and better overall strength, making them less prone to cracking or breaking under heavy use. Additionally, since forging involves shaping metal using compressive forces, it aligns the grain structure of the material with its shape, resulting in a stronger and more durable part.
Conclusion
While both casting and forging have their advantages and disadvantages, when it comes to producing trunnions for the WASR, forging is the preferred method for high strength and durability. Though it may be more expensive and require more time, the quality of a forged trunnion is worth the investment for a reliable and long-lasting firearm.
