Zenitco Sport-4S Handguard Kit – AK Handguard System (Long Barrel, Basis)
CNC-Machined D16T Aluminum | Basis Rails (Picatinny on 3 Sides) | Improves Barrel Cooling | 350 g
The Zenitco Sport-4S Kit is a complete handguard system that replaces the standard handguard on long-barrel (415 mm) AK-pattern sporting platforms and carbines built on them. Its Basis guide accepts B-2, B-2L, B-2U and A-1L brackets that form Picatinny rails on three sides for mounting accessories.
It improves barrel cooling along the section from the receiver to the gas tube and keeps weight and bulk to a minimum. A lighter-rail version, the Sport-4, is also available.
? Compatibility & Use Notes
- For long-barrel (415 mm) platforms only. Not compatible with short-barrel versions (314–350 mm) — for those, use the Sport-1 kit.
- A cleaning rod cannot be mounted in its standard position with this kit installed.

- Picatinny on 3 sides – via Basis brackets (B-2, B-2L, B-2U, A-1L)

- Lightweight – 350 g, minimal bulk
