The fourth and final installment in the SIG MCX® video series unveils the SIG MCX Rattler, a rifle designed shorter than any M4 ever produced. Built at the request of elite military units, the SIG MCX Rattler offers M4 ballistics in a subgun-sized package. With a 5.5” barrel and overall length of only 16” when folded, the SIG MCX Rattler rewrites the possibilities for ultra-compact firepower.
