G43 Bolt Housing Retainer

The G43/K43 Bolt Housing Retainer is a locking component that secures the bolt housing to the rear of the receiver. Working together with the rear recoil spring guide, it prevents the bolt housing from moving during operation while still allowing quick field disassembly when the recoil spring guide is compressed.

The retainer is subjected to continuous mechanical loads every time the rifle cycles. Over many years of use, the engagement surfaces can become rounded or worn, resulting in excessive play between the receiver and the bolt housing. Replacing the retainer helps restore the original fit of the bolt assembly and ensures that the bolt housing remains correctly secured during firing.

Manufactured to closely match the original wartime dimensions, this G43/K43 Bolt Housing Retainer provides accurate engagement with both the receiver and the recoil spring guide. The component is machined from high-quality steel for excellent strength and durability, making it suitable for maintenance, professional restoration, or replacing a damaged original part while preserving the original operating principle of the rifle.
