Sig Sauer MCX Spear-LT IR Features
The MCX Spear-LT IR operates on a gas piston system, offering smoother cycling and reduced recoil for enhanced control. Its fully ambidextrous controls, including an ambidextrous safety lever, make it an ideal firearm for both left- and right-handed shooters. The flat-blade match trigger delivers a crisp, consistent pull, improving precision and handling.
For superior modularity, the M-LOK handguard allows users to mount accessories such as lights, grips, and lasers. The QD flash hider on the threaded barrel (1/2″x28) enables quick attachment of suppressors or muzzle devices. Designed with an optics-ready Picatinny rail receiver, users can mount their preferred sighting system for increased accuracy. Weighing just 6.68 lbs., the MCX Spear-LT IR maintains a well-balanced feel for dynamic engagements.
