The ZB-2U Z Sport Rail manufactured by LCT is the extended version of the ZB-2 adapter, designed to offer a wider mounting surface (7.5 cm) on modern modular handguards.
Dual Compatibility (Zenitco + M-LOK):
As with the short version, the great advantage of this kit is the presence of two sets of attachments included. This makes the rail universal: it can be installed on both specific Zenitco Style handguards (LCT ZK-12, ZK-12U, Zsport series) and any handguard equipped with the M-LOK standard.
Construction and Dimensions:
Made entirely of metal, this long version measures 7.5 cm. This extra length makes it perfect for hosting accessories that require more slots, such as vertical grips, bipods, or extended remote switches, while maintaining a light weight of only 20 grams.
