The M25 sniper weapon system is a joint venture precision rifle built for the U.S. Army Special Forces and the U.S. Navy SEALs.

It was originally developed by the 10th Special Forces Group, based at Fort Devens, Mass., to fulfill a requirement for a sniper rifle based on a match grade M14 that satisfied the requirements of the Army Special Forces and the Navy SEALs.

[2] The commercial version has been named "White Feather" in honor of Carlos Hathcock, the U.S. Marine Corps sniper who became famous during the Vietnam War.

The M25 is not a replacement rifle for the M24 sniper weapon system; it was designed to fill a specific need for accurate fire beyond the range of a standard-issue carbine and has been used from the Persian Gulf War onwards as the designated marksman's rifle (DMR).

It has a National Match M14 barrel in a McMillan glass bedded fiberglass stock, uses a special gas piston, a National Match spring guide and a Brookfield Precision Tool Advanced Scope Mounting System.
