Sport-4 B33 Top Cover Handguard Kit for Tokyo Marui 5KU AKM GBBR

The 5KU Sport-4 B33 Top Cover AKM GBBR handguard kit is a complete replacement set, designed specifically for the Tokyo Marui AKM GBBR. Faithfully replicating the Zenitco Sport-4 style, this kit stands out for its construction made entirely of CNC-machined aluminum, which offers a superior finish and rigidity compared to polymer solutions. It represents a first-rate aesthetic and tactical upgrade for players looking to give their replica a look inspired by Z-series configurations.

The kit includes several components: a B-31LV handguard, a B-33 top cover, and a CNC-machined outer barrel, all compatible with the B-2 modular rail system.

For owners of a Tokyo Marui AKM GBBR looking for a cohesive and structured visual upgrade, this kit offers a complete solution directly inspired by real-world equipment.
