This Sport-4 kit is a smart, modular aluminum rail system designed for full-size AK replicas (e.g. AK-74, AK-74M, AKMS and AKM). Please note: it is not compatible with shorter models such as the AK-105. The lightweight design lets you fully customize your AK to suit your individual needs.

The system is based on the B10L handguard and includes a set of overlays and an extension so you can adjust the overall handguard length as required. Both the handguard and the extension use a Zenitco mounting interface that is compatible with KeyMod and M-LOK, giving you flexible mounting options for rails and accessories. The B-31LW gas tube overlay features two sections of 35 mm rail, providing a stable platform for accessories like a red dot, AN/PEQ unit, or PERST module.
