G3 Rear Sight Screw Washer

G3 Rear Sight Lock Washer

This small toothed washer sits under the clamping screw of the G3 rear sight and keeps that screw from backing out under recoil. If yours is missing, flattened, or lost during a strip-down, the sight can shift and your zero goes with it. It is German Army issue hardware for owners, builders and armorers keeping a G3 or G3-pattern rifle correct.

Features

• External-Tooth Lock Washer — Serrated teeth around the outer edge bite into the screw head and the mating surface, so vibration has a harder time working the screw loose.
• Hardened Steel Construction — Hardened steel lets the teeth hold their shape under clamping torque instead of flattening out.
• Dark Finish — The black finish matches the rest of the rear sight hardware on a G3.
• Rear Sight Clamping Screw Fit — It goes under the screw that clamps the rear sight assembly to the receiver.
• G3 Pattern Compatibility — It fits the G3 rear sight and the matching sight hardware on the HK91, PTR 91, PTR32, HK93, HK94, HK21 and MP5.
• German Army Issue — This is genuine Bundeswehr rifle hardware made to the original military specification.
• Small Spare Worth Keeping — It is easy to lose during disassembly, so a spare in the parts bin saves a stalled rebuild.

German Army Issue

The washer comes from Bundeswehr stocks of G3 rifle parts and was made to the same specification as the hardware fitted at the factory. Using the issued part keeps the rear sight assembly to the original standard, which matters to builders and collectors putting together a correct rifle. Compare it with your existing washer before fitting, since sight hardware on G3-pattern clones can vary between makers.
