The MCX SPEAR-LT IR by Sig Sauer is the next generation of the renowned MCX platform. What sets the MCX SPEAR-LT IR apart from the other firearms in the MCX family is a Cerakote II IR coating. This innovative finish both protects the weapon from weathering and helps conceal it from night vision or thermal imagers. Just like the standard versions, the MCX SPEAR-LT IR combines the lightweight modular design of the MCX Gen 1 with the durability of the MCX VIRTUS, resulting in a system that is lightweight, durable, modular, and accurate. To ensure maximum ruggedness and rigidity, the MCX SPEAR-LT’s handguard incorporates 2 additional screws in the handguard to provide maximum deflection capabilities, allowing more accessories to be added to the handguard without interfering with the rifle’s point-of-aim/point-of-impact. The handguard is also lighter than prior versions, and was designed with an emphasis on ergonomics. Similar to the handguard, the barrel has a reduced weight but has a slightly larger contour, promoting greater accuracy without adding unnecessary weight.
