The SIG Sauer MCX SPEAR-LT expands on the success of the MCX platform by fulfilling the demands of the community. SIG listen closely and delivered by adding a ton of new features a that users have been asking for. SIG updated their lightweight handguard to be more slimlined added fully ambidextrous controls, and are now compatible with standard AR-15 style triggers allowing for even more customization. However, even though you now have more trigger options you may not want to change it out, the included flatblade match trigger features a light pull with a slight take-up, a well defined wall, and a clean break. The new fully ambidextrous lower receiver is a huge benefit allowing you to easily manipulate the fire selector, magazine release, and the bolt release no matter what your strong hand is. Most notably, the new handguard reduces weight with a slimer profile improving ergonomics and the improved attachment method helps to increase rigidity allowing you to take full advantage of the accuracy from the lightweight profile barrel. The SIG MCX SPEAR LT features a coyote brown anodizing and will make a great addition to your collection.
