New for 2022, the MCX SPEAR-LT by Sig Sauer is the next generation of the renowned MCX platform. Building off the success of its predecessors, the MCX SPEAR-LT 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. The barrel is topped with a QD Flash Hider and uses a proprietary Cluth-Lock design for use with a suppressor.
Other features of the MCX SPEAR-LT include a newly designed lower which features fully ambidextrous controls such as a M400 style bolt catch, and is compatible with standard MCX and MCX VIRTUS upper receivers. The MCX SPEAR-LT’s trigger is the Matchlite Duo, but a firing pin latch in the bolt carrier allows an AR15 style trigger or any MCX trigger to be used. In addition, this variation of the MCX SPEAR-LT is chambered in 7.62x39, a cartridge never before seen in the MCX family. To handle the new cartridge, 7.62x39 versions of the MCX SPEAR-LT are reengineered with a new latch system, allowing the weapon to reliably cycle ANY type of 7.62x39 cartridge.
