G3 Buffer End Cap Screw

German G3 Buffer Part

This is a German Army issue buffer end cap screw for the G3 battle rifle, the 7.62x51mm NATO service rifle of the Bundeswehr (the post-war German armed forces). It threads into the buffer end cap and holds the buffer spring and internal parts in place, keeping the recoil assembly captured under tension. Owners rebuilding a G3, HK91 or PTR91 and collectors completing a spares kit are the people who go looking for this part.

Features

• German Army Issue — The part comes from Bundeswehr G3 stores and is original government-issue rifle hardware.
• Buffer Assembly Retention — It secures the buffer spring and internal components inside the end cap so the recoil buffer stays seated.
• Built For Full-Power Recoil — The assembly it retains absorbs recoil from full-power 7.62x51mm NATO ammunition.
• Steel Construction — The body is machined steel, which holds its threads under repeated loading.
• Black Finish — A dark, corrosion-resistant finish matches the rest of the G3's metal parts.
• Threaded Center Bore — A machined internal thread runs through the middle of the round, flanged body.
• Rim Notches — Two small slots cut into the outer edge of the face are visible on the part.
• G3-Pattern Compatibility — It fits the HK G3 and its semi-automatic derivatives, the HK91 and PTR91.

Issued G3 Hardware

The G3 was Germany's standard service rifle for decades, and this screw is part of the recoil buffer system in its stock configuration. Because it came from army stores, it was made to the military's own specification and not to an aftermarket maker's version of it. A small part like this is easy to lose during a stock swap or buffer service, so keeping an issued spare on hand makes sense for anyone who works on their own G3-pattern rifle.
