G43 Actuator rod

The G43/K43 Actuator Rod is the final link in the rifle's gas operating system. After the gas cylinder has been driven rearward, the force is transferred through the connecting rod to the actuator rod, which then pushes the bolt carrier to the rear and initiates the complete operating cycle of the rifle.

Because the actuator rod transfers all operating forces from the gas system to the bolt carrier, it is exposed to repeated impact loads during firing. A bent, worn or damaged actuator rod can reduce the efficiency of the gas system and may result in inconsistent cycling or increased wear on other components.

This replacement G43/K43 Actuator Rod is manufactured to original military dimensions, ensuring correct alignment with the connecting rod, bolt carrier and recoil system. The accurately machined contact surfaces provide smooth energy transfer while maintaining the original mechanical operation of the rifle. Whether replacing a worn component or rebuilding the complete gas system, this actuator rod offers a reliable solution for restoring proper function.
