G3 Rear Sight Oval Washer

G3 Rear Sight Washer

This is the small oval washer from the rear sight assembly of the HK G3, the German service rifle chambered in 7.62x51mm NATO. It sits in the drum rear sight and works with the locking washer, so a missing or damaged one can stop a sight rebuild. G3 and HK91 owners, builders, and armorers refurbishing roller-delayed rifles keep this part on hand for that reason.

Features

• Oval Flat Washer — A flat metal washer with an oval outer profile and a rounded-rectangle center opening, made to seat in the G3 rear sight.

• Pairs With Locking Washer — Installs together with the rear sight locking washer as part of the diopter assembly.
• German Army Issue — Original Bundeswehr-issue hardware built to German military specification, the army's own published standard for the part.
• Heckler & Koch Pattern — Made for the HK G3 rear sight assembly used on German military service rifles.
• Wide HK Family Fit — Listed for G3, HK91, PTR91, HK93, HK94, MP5, and HK21 rear sight assemblies that share the drum sight design.
• Rebuild And Replacement Part — Suited to rear sight rebuilds, refurbishment, or replacing a washer lost during disassembly.

Bundeswehr Issue Hardware

This washer is genuine German Army stock produced for the G3, not an aftermarket copy cut to approximate dimensions. That matters on a sight assembly, where small parts have to fit the original drum and locking hardware as designed. Builders working on HK clones such as the PTR91 get the same factory-pattern part that went into issued rifles. The washer is sold on its own, without the rest of the sight assembly.
