G3 Hammer Spring

G3 Hammer Spring

This is the hammer spring for the G3 battle rifle, taken from German Army parts stocks. It is the coil spring inside the trigger group that powers the hammer forward to strike the firing pin. A weak or tired hammer spring can give light primer strikes, so this is one of the first parts G3 owners and armorers replace when a rifle starts misfiring. It is also a useful spare for anyone keeping a G3-pattern rifle running for the long haul.

Features

• Genuine German Army Issue — Supplied from Bundeswehr G3 parts stocks, so it is an original military part rather than an aftermarket substitute.
• Hammer Drive Spring — It compresses as the hammer is cocked and releases that stored energy to snap the hammer into the firing pin when the trigger breaks.
• Coil Compression Spring — A tightly wound steel coil built to be squeezed and to push back, which is the job a hammer spring does on every shot.
• Plain Steel Finish — Bare steel wire with no paint or coating to flake off inside the trigger housing.
• Closed Coil Ends — The end coils are wound tight so the spring sits squarely against its seats.
• G3 Trigger Group Part — Made for the hammer assembly in the G3 trigger group, where it fits in place of the original spring.
• Single Spring — You receive one hammer spring only, with no hammer, guide or other trigger parts included.

Bundeswehr Issue Part

The G3 is the Heckler & Koch rifle in 7.62x51mm NATO that served as the German Army's standard service rifle for decades. Spare parts like this one were made to the army's own specification for keeping those rifles in service. Fitting an issue spring keeps a G3 build true to the original, which matters to collectors and restorers as much as it does to shooters.
