Also known as: C15 LRSW, C15A1, C15A2, Mk 15, Long-Range Sniper Weapon
Overview
The McMillan TAC-50 is a long-range anti-materiel and sniper rifle chambered in .50 BMG (12.7x99mm NATO), designed and manufactured by McMillan Firearms in Phoenix, Arizona. Based on the earlier McMillan M87R design originally produced by Harris Gun Works, the TAC-50 features a manually operated rotating bolt action, a 737mm (29-inch) match-grade fluted stainless steel barrel manufactured by Lilja, and a fiberglass stock with adjustable cheek piece and buttpad in a take-down configuration. The rifle feeds from a 5-round detachable box magazine and employs an effective muzzle brake to manage the substantial recoil of the .50 BMG cartridge. The TAC-50 is guaranteed to produce 0.5 MOA accuracy with match-grade ammunition under ideal conditions. Adopted by the Canadian Armed Forces as the C15 Long-Range Sniper Weapon in 2000 and by the US Navy SEALs as the Mk 15, the TAC-50 has established itself as one of the premier extreme long-range precision rifles in the world, with multiple record-breaking engagements to its credit.

Notes
The Canadian Armed Forces designation has evolved with the rifle's variants: C15 for the original TAC-50 (adopted 2000), C15A1 for the TAC-50 A1 (upgraded 2014), and C15A2 for the TAC-50C (upgraded 2017). The TAC-50C variant introduced an improved stock design and enhanced accuracy features. The rifle is designed to be used exclusively from a bipod due to its weight and recoil characteristics. The stock features a take-down design for transport. The fluted barrel by Lilja is designed to dissipate heat rapidly while reducing overall weight. The TAC-50 held the record for the longest confirmed sniper kill from 2017 to 2023, when the record was surpassed by a Ukrainian sniper using a domestically produced rifle at 3,800 meters.
Background
The McMillan TAC-50 is associated with several of the longest confirmed sniper kills in history. In March 2002, Canadian Corporal Rob Furlong of the 3rd Battalion Princess Patricia's Canadian Light Infantry used a TAC-50 to eliminate a Taliban combatant at 2,430 meters in Afghanistan's Shah-i-Kot Valley during Operation Anaconda, setting a world record that stood for seven years. In June 2017, an unnamed Canadian Joint Task Force 2 sniper shattered all previous records by killing an ISIS fighter at 3,540 meters (2.2 miles) in Iraq, a shot that took approximately 10 seconds of flight time and required accounting for the curvature of the Earth. This record stood until November 2023.
