"What we’ve done is taken away that guy and his ability to seek cover, forever. We don’t actually need to hit him; we can have the round fly over him and explode down," said Lt. Col. Christopher Lehner, a four-tour veteran of the Iraq and Afghanistan wars who is the project manager for individual soldier weapons at the arsenal. By firing bullets that can explode at distances up to nearly a half-mile, the 12½-pound rifle holds the potential to solve an age-old inadequacy in individual firearms: the need to have a target in the line of sight in order for it to be taken down.
