M40

The M40 was a type of sniper rifle used by the United States military.

Al Crenshaw's weapon of choice was an M40 - during Operation Nightfall he had to use a Dragunov rifle instead, and claimed he would prefer to have been using his M40.

The CTU standard issue sniper rifle was the PSG-1 Sniper Rifle rather than the M40A3, as the PSG-1 had enhanced accuracy over shorter ranges.
