INFITAC FAST Mini FML19 Thermal Sight
PLEASE INQUIRE FOR CURRENT STOCK STATUS OR LEAD TIME PRIOR TO ORDERING
The INFITAC FAST Mini FML19 is an ultra-compact, yet affordable, thermal optic designed for pistol, compact rifle, SBR, and shotgun applications, delivering enhanced detection capability in a minimal footprint. Built around a 384 × 288, 12 µm thermal sensor operating at 60Hz, the FML19 provides improved image detail and target recognition in a highly compact form factor.
Paired with a 19mm F/1.0 germanium lens, the FML19 offers increased detection range while maintaining a field of view optimized for close to mid-range shooting distances. The system is engineered for speed and simplicity, allowing users to quickly identify and engage targets without unnecessary complexity. The 1.4” display is designed to be viewed at normal pistol shooting extension making it unique from traditional thermal optics that require a very short eye relief and only work on rifles.
The compact housing is designed for hard-use applications and is rated to withstand recoil across pistol, rifle, and shotgun platforms. Its small size and lightweight design allow for seamless integration without significantly impacting balance or handling on compact weapon systems. Additionally, it is IP67 waterproof and dustproof for use in challenging weather conditions.
The FML19 comes standard with a Trijicon RMR footprint interface, allowing direct mounting to a wide range of RMR-ready applications. Additional INFITAC offers other mounting options such as Picatinny, 30mm Ring, 45° Offset, RMSc, Delta Point PRO, Aimpoint ACRO, and Glock MOS to provide flexibility across almost any desired weapon platform or configuration.
This optic utilizes a simplified, touch screen control interface allowing the user to adapt quickly to changing environmental conditions or preferences. Power is supplied by a rechargeable CR2 battery, providing approximately 5 hours of runtime while maintaining a streamlined profile. Additionally, InstaWake Technology allows it to remain in a standby mode and then instantly activate upon motion without pressing any buttons, while remaining in a power saving state. A USB-C interface allows for external power input for even longer operating times.
The INFITAC FAST Mini FML19 is built for rugged use and is backed by a three-year warranty with an additional six months upon user registration, so buy with confidence knowing you’ll be able to enjoy this optic for many years of reliable use.
