Lancer Tactical Reactor Slide Kit Glock 19 GBB

A premium slide kit for Glock 19 GBB replicas

This kit is designed for airsoft players looking to upgrade their Glock 19 GBB Gen 5 replica. Inspired by the famous Arc Division Reactor slide, it combines aggressive aesthetics with mechanical optimization. Once installed, it transforms the replica's appearance and responsiveness while maintaining smooth operation.

CNC machined aluminum

The cylinder head is CNC-machined from aluminum , a process that guarantees precision and robustness. This construction offers an excellent compromise between strength and weight, allowing for a fast and consistent cycle during gas blowback operation. The visual appearance is also more realistic and high-end.

Reactor design with ported external cannon

The design faithfully replicates the Arc Division Reactor configuration with characteristic cutouts on the bolt. Combined with the ported outer barrel , this assembly reduces the bolt's moving mass, which can improve cycle speed and the feel of firing during rapid bursts in-game.

Modern optical configuration

The receiver is optics-ready thanks to an included RMR mounting plate . This allows players to easily install a micro red dot sight to improve target acquisition. The height suppressor sights enable co-witness with the optic mounted, ensuring a reliable aiming solution even if the optic fails.

Simple drop-in installation

The kit is designed for easy installation on Elite Force / Umarex Glock 19 GBB Gen 5 replicas. The drop-in configuration minimizes modifications and allows for quick transformation of the replica with a complete set including slide, outer barrel, and essential parts.
