Benefits & Use Cases
The MCX-SPEAR LT IR is tailored for operations where stealth and low detectability are crucial. Thanks to its infrared-reducing Cerakote, it’s ideal for low-light or night-vision environments. Meanwhile, its modular design (interchangeable barrels / handguards) makes it highly adaptable — whether for tactical, law-enforcement, or professional applications. The folding stock and lightweight build also make it effective for mobile or confined operations.
Reliability & Durability
The advanced short-stroke piston system and cold hammer-forged barrel ensure robust performance, even in demanding conditions. The Cerakote Gen II finish not only reduces IR signature, but also provides superior corrosion and wear resistance.
