Galil trunnions are integral components of the Stamped Galil series of rifles, including variants such as the Galil ARM, Galil SAR, and Galil AR. Here's some information about Galil trunnions:
-
Definition and Function:
A trunnion is a structural component that connects the barrel to the receiver of a firearm. In the case of the Galil rifles, the trunnion serves as a crucial attachment point for the barrel assembly. It provides stability, alignment, and structural integrity to ensure consistent and reliable performance.
-
Construction and Material:
Galil trunnions are typically machined from high-strength steel, chosen for its durability and ability to withstand the forces generated during firing. The final machined part is then heat treated to ensure longevity and strength. The steel used in trunnion construction is carefully selected to withstand the stresses and pressures associated with the specific caliber and intended use of the rifle.
-
Assembly and Attachment:
During the manufacturing process, the Galil trunnion is precisely fitted and riveted in the receiver, ensuring proper alignment and stability. The barrel is then pressed into the trunnion and then drilled and pinned like a normal AKM build.
-
Impact on Accuracy and Reliability:
The quality and precision of the trunnion assembly play a critical role in the overall accuracy and reliability of the Galil rifle. A well-constructed and properly installed trunnion ensures consistent barrel alignment, reducing any potential for movement or shifting during firing. This contributes to improved accuracy and repeatable performance.
