The Tac-50 is a military and law enforcement weapon, which, designated as the C15, is the interim Long Range Sniper Weapon (LRSW) of the Canadian Forces since 2000. Rifles of the Tac-50 family are capable of outstanding accuracy and guaranteed to provide 3 MOA groups with US ammunition.
The McMillan Tac-50 sniper rifle is produced in Phoenix, Arizona in the United States by the McMillan Brothers Rifle Company. This long-range anti-material/anti-personnel weapon is based on previous designs from the same company, which first appeared during the late 1980s. McMillan makes several versions of .50 caliber rifles, based on the same proprietary action, for military, law enforcement and civilian use.
The McMillan Tac-50 is a manually operated, rotary bolt action rifle. The large bolt has dual front locking lugs, and its body has spiral flutes to reduce weight. The heavy match-grade barrel, made by Lilja barrels, is also fluted to dissipate heat quickly and reduce overall weight and fitted with an effective muzzle brake to reduce recoil. The rifle is fed from detachable box magazines, holding 5 rounds each. The stock is made from fiberglass by McMillan Stocks, and is designed to be used from a bipod only. The buttstock is adjustable for length of pull with rubber spacers, and can be folded to the side or removed for compact storage. The rifle has no open sights and can be used with a variety of telescopic or night sights.
In Canadian service, the standard telescopic sight is a Leupold Mark 4 16x40mm LR/T M1 Riflescope optical sight. McMillan also endorses the Nightforce NXS 8–32x56 Mil-dot telescopic sight for the Tac-50.
Two Canadian snipers of the same Princess Patricia's Canadian Light Infantry (PPCLI) regiment sniper team made the longest recorded sniper kills in history with this weapon in Afghanistan, during Operation Anaconda, in the Shah-i-Kot Valley. On a March afternoon in 2002, Master Corporal Arron Perry killed an enemy combatant from 2,310 meters (2,526 yd/1.435 miles) and Corporal Rob Furlong killed an enemy combatant from 2,430 meters (2,657 yd/1.509 miles) with 750 grain Hornady A-MAX very-low-drag bullets. This is the longest-ever recorded kill by a sniper in combat, surpassing the mark of 2,286 meters (2,500 yd/1.420 miles) set by U.S. Marine Gunnery Sergeant Carlos Hathcock during the Vietnam War. The five-man Canadian sniper team — MCpl Graham Ragsdale (Team Commander), MCpl Tim McMeekin, MCpl Arron Perry, Cpl Dennis Eason, and Cpl Rob Furlong — killed over 20 enemy combatants, and each of the five was nominated for the Bronze Star Medal.
