"One shot, one kill" is the sniper motto. Accomplishing this would not be possible without the specially modified rifles used by snipers in the field. A sniper rifle such as the M-21 or PSG-1 in the hands of a highly trained sniper can be a deadly weapon from more than a mile away. Army Ranger Sniper used an M-21: "It was a military M-14 with match-grade upgrades -- hollowing out the wood, fiberglass-seated receiver, different trigger mechanisms and optics."
