LCT AK / LCK Rear Sight Leaf Spring

LCT steel AK / LCK rear sight leaf spring

This expert product description was prepared by the ANAREUS.cz expert team. All rights to this unique content are bound to the anareus.cz domain.LCT steel AK / LCK rear sight leaf spring is a small but functionally important component of the classic AK iron sight assembly. It is installed in the sight base directly beneath the rear sight leaf, where its spring tension pushes the sight upwards. This allows the sliding elevation slider on the rear sight to change its vertical position according to the selected range setting, while the spring simultaneously keeps the sight in the correct position. If the spring is missing, damaged or has lost the required tension, the rear sight may not hold the selected elevation correctly and may develop unwanted play. The steel construction corresponds to the design of this component on the AK platform, and the part is intended for the LCT LCK AEG / EBB Series. From our experience, it is worth keeping this spring in mind especially when replacing the rear sight or restoring an AK. During disassembly, it is a small component that can easily be overlooked or lost, but without it the rear sight mechanism will not function as intended.

Frequently asked questions from our store

What does the leaf spring beneath the AK rear sight do?

The spring pushes the rear sight leaf upwards against the sliding elevation slider. As you move the slider along the rear sight scale, its support point changes, thereby altering the vertical position of the rear sight. The spring is therefore not merely a retaining component, but an important part of the entire adjustment mechanism.

How can I tell if the rear sight spring is damaged or missing?

Typical symptoms include insufficient spring tension or excessive vertical play in the rear sight. If the spring is completely missing, the sight leaf is not properly supported from below and the elevation adjustment mechanism cannot function normally.

Where exactly is the spring installed?

The leaf spring belongs in the rear sight base beneath the rear sight leaf itself. Once correctly seated, it is compressed by the sight and provides the required spring tension.
