The RC-50 is an anti-materiel rifle of US origin. It was originally developed by Robar for civilian target shooting at long ranges. Since 12.7mm rifles started to be used by the military the RC-50 is also marketed for law enforcement and military use. The RC-50 is also called a counter-sniper rifle.
The RC-50 is a bolt action rifle of a conventional design. The long and fluted barrel is fitted with a highly efficient muzzle brake, which is notably smaller than most muzzle brakes on 12.7mm rifles. The bolt is machined out of a single block of metal. A McMillan fiberglass stock is used and a bipod is fitted as standard.
The RC-50 fires the 12.7x99mm round from a 5 round detachable box magazine. As a bolt action rifle its rate of fire is limited. Due to its long and heavy barrel its accuracy is very good and sub MOA accuracy can be achieved. With match ammunition targets out to 2.000 m can be engaged.
The RC-50 is used by various law enforcement agencies in the USA, including the US Coast Guard.
