G3 Rear Sight Clamping Screw

German G3 Sight Screw

This is the clamping screw that holds the G3 rotary drum rear sight to its mounting base at the back of the receiver. The drum sight is a rotating cylinder with apertures for different ranges, and it needs a firm clamp to hold zero under recoil. If yours is missing, stripped or chewed up, this German Army part puts the sight back together the way it was issued. G3 owners, HK91 and PTR-91 builders, and collectors keeping a rifle correct all use it.

Features

• German Army Issue — Originally supplied for Bundeswehr G3 service rifles, so it is the factory specification part rather than an aftermarket substitute.
• Rear Sight Clamping Role — Secures the rotary drum rear sight assembly to its base on top of the receiver.
• Hardened Steel Construction — Made from hardened steel to keep its threads and head intact through repeated tightening.
• Precision-Machined Threads — Cut to the original military dimensions so it threads cleanly into the factory sight base.
• Cross-Recess Head — A domed head with a crossed slot takes a standard cross-point screwdriver.
• Serrated Head Rim — The outer edge of the head carries a row of serrations, as seen on the issued part.
• Black Finish — A dark finish matches the rest of the G3 sight hardware.
• Made In Germany — Produced in Germany for German military rifles.

Fit And Specification

The screw is made for the G3 rear sight and is also listed as compatible with HK91, PTR-91, HK93, HK94, MP5 and HK21 rear sight assemblies that use the same drum sight. It is a single screw with a short threaded shank, sold as a replacement part. Compare it with your existing hardware before fitting if your rifle is a commercial clone built to its own pattern.
