Zenitco Sport-4S Handguard Kit
Genuine Zenitco | Reinforced version of the Sport-4 kit | One-piece CNC D16T aluminum | Basis rails forming Picatinny on three sides | For full-length AK-pattern carbines | Black & Desert
In short: the Zenitco Sport-4S is a modular handguard kit that replaces the factory handguard on full-length AK-pattern carbines. It is the reinforced version of the Sport-4 kit, with a strengthened lower Basis rail. It carries a Basis rail for mounting B-2, B-2L, B-2U and A-1L brackets that form Picatinny on three sides.
Overview
Sport-4S is the reinforced Sport-4: the B-10LS handguard with the strengthened lower Bazis guide, the B-31LV rail over the gas tube and the DL-2S extension insert.
It fits AK-pattern carbines with a 415 mm barrel and their civilian counterparts. The plain Sport-4 uses the lighter lower guide; this one is for builds that load the underside.
