We have seen some cool iPhone applications come out for shooting sports. But nothing comes close to the sheer awesomeness of the Knights Armaments M110 iPod Touch mount and accompanying ballistics software.
The M110 is the 7.62×51mm semi-automatic sniper system which won the Army’s competition to replace the aging M24 bolt action sniper system. While it will not replace the M24 in the near future, the system is seeing action in Iraq and Afghanistan.
