What specific sight is the Lyman 16c Sight Blade Retaining / Elevation Screw compatible with?

This screw is designed exclusively as a replacement part for the Lyman No. 16C Folding Leaf Open Rear Sight. It is a precise OEM component to ensure proper function and fit for that specific vintage sight model.

What is the primary function of this screw on the Lyman 16C sight?

The screw serves a dual purpose: it acts as the retaining screw that clamps the adjustable elevation blade to the folding leaf, and it allows the shooter to loosen, slide, and lock the blade for precise elevation adjustments. It is also critical for securing the reversible 'V' or 'U' notch blade in your preferred orientation.

Why would I need to purchase a replacement for this specific screw?

Due to its micro-size, this screw is easily lost during field adjustments, cleaning, or disassembly of your Lyman 16C sight. This OEM replacement allows for the restoration of vintage or modern Lyman 16C sights to full working order, preventing the use of mismatched or incorrect hardware.

Will this screw fit my rifle, such as a Winchester Model 70 or Savage Model 110?

This screw is a component of the Lyman No. 16C Folding Leaf Open Rear Sight, not a direct rifle part. The Lyman 16C sight itself is commonly used on classic rifles like the Pre-64 Winchester Model 70 and Savage Model 110, which feature a standard 3/8" dovetail slot.

Does this screw require any special Australian certifications or electrical considerations?

No, as a purely mechanical firearm component, the Lyman 16c Sight Blade Retaining / Elevation Screw does not require 240V power, SAA/RCM safety certifications, or an Australian power plug. It is a non-electrical accessory.
