The Oracle Gen:X Built around ACETECH. The Oracle Gen:X Upper represents the next evolution in tracer technology, delivering enhanced performance and reliability for airsoft enthusiasts. This standalone upper receiver allows you to seamlessly upgrade your existing Oracle platform to the latest generation without replacing your entire setup. Engineered for precision and durability, the Gen:X Upper is compatible with two premium tracer systems: the Acetech Quadra and the Brighter-C, giving you flexibility in choosing your preferred tracer unit. Both options integrate seamlessly with this upgraded upper, ensuring optimal performance and consistent operation during extended gameplay. Available in both 5-inch and 6-inch configurations, you can select the length that best suits your tactical setup and playstyle. The 5-inch variant offers enhanced maneuverability in tight spaces, while the 6-inch provides extended sight radius and improved accuracy at distance. Built with the same attention to detail that defines Monk Customs, the Gen:X Upper features improved internals, refined ergonomics, and enhanced reliability.
