Maztech X4-FCS 34mm Fire Control System - Black/Green

The Maztech X4-FCS is a 34mm Fire Control System that transforms a standard low-power variable optic into an advanced, sensor-driven ballistic computer. Built around a solid billet aircraft-grade 7075-T6 aluminum housing finished in black with a green display, this smart optic clamps onto most 30mm and 34mm LPVO scopes and adds real-time environmental sensing, integrated ballistics, and wireless connectivity without forcing the shooter to swap glass.

Designed to meet MIL-STD-810 environmental specifications, the X4-FCS integrates a ballistic solver for auto-calculated firing solutions and pairs it with on-board environmental sensors. Wireless connectivity includes Bluetooth Low Energy, NFC, and UWB, giving the unit broad compatibility with external devices and accessories across the X4 ecosystem. Power is provided by two rechargeable 18650 batteries charged via USB-C, and the integrated sleep/wake management delivers approximately one year of battery life at roughly 10 hours per week of use.

This listing is for the 34mm tube version, part number MZT001-34-AB-BLK/GRN, in a black housing with a green display. The package includes two rechargeable 18650 batteries, two USB-C charging cables, and a lens cleaning cloth.
