Army might have found its new rifle in Colorado Springs garage

The Army adopted its battle rifle in 1963 and has spent 55 years looking for a replacement for the M-16 and its variants.

All firearms shoot in an arc that corresponds to the up-down of the gun, right? So, to shoot around corners, just turn the gun sideways!
(That's why homies hold their guns sideways -- they are aiming behind obstacles, urban environment and all)
