The 5KU K-31C Classic Top Rail for AK – Tan is a high-quality aluminium top rail designed for AK airsoft replicas equipped with a B-30 handguard system. It adds modern accessory mounting capability while maintaining the classic AK appearance.
Manufactured from lightweight and durable aluminium, the K-31C Classic Top Rail provides a realistic reproduction of Russian-style AK accessories. It improves both the functionality and appearance of AK platforms by creating an additional mounting platform for tactical equipment.
The integrated 22 mm RIS/Picatinny rail allows users to mount a wide range of accessories including red dot sights, optics, tactical lights, lasers and other compatible equipment. This makes it a practical upgrade for modern AK builds.
The rail attaches directly to the B-30 handguard using the included mounting screws. It is compatible with many AK replicas based on the VFC system, including platforms from VFC, BOYI, CYMA, E&L and LCT. Compatibility should always be checked before installation, as minor fitting may sometimes be required.
The Tan finish provides a modern military appearance and pairs perfectly with other FDE, tan and Zenitco-inspired AK upgrades.
