<P> The FN Patrol Bolt Rifle has the standard features of the original Winchester Model 70 rifle but the rifle is designed for use by police officers in patrol cars with the rifle having a short and compact barrel so it would allow the rifle to be stored in a police car . The FN Patrol Bolt Rifle is also marketed with a compensator on the muzzle of the rifle's barrel . </P> <P> The United States Marine Corps purchased 373 Model 70 rifles in May, 1942 . Although the Marine Corps officially used only the M1 Garand and the M1903 Springfield as sniper rifles during the Second World War, "many Winchester Model 70s showed up at training camps and in actual field use during the Pacific campaign ." These rifles had 24 - inch sporter barrels chambered for . 30 - 06 Springfield . They were serial numbered in the 41000 to 50000 range and were fitted with leaf sights and checkered stocks with steel butt plates, one - inch sling swivels, and leather slings . It has been reported that some of these rifles were equipped with 8X Unertl telescopic sights for limited unofficial use as sniper weapons on Guadalcanal and during the Korean War . Many of the surviving rifles, after reconditioning with heavier Douglas barrels and new stocks between 1956 and 1963 at the Marine Corps match rebuild shop in Albany, Georgia, were fitted with 8 × Unertl sights from M1903A1 sniper rifles . The reconditioned rifles were used in competitive shooting matches; and the United States Army purchased approximately 200 new Model 70 National Match Rifles with medium heavy barrels for match use between 1954 and 1957 . Many of the reconditioned Marine Corps match rifles were used by Marine Corps snipers during the early years of the Vietnam war with M72 match ammunition loaded with 173 - grain boat - tailed bullets . A smaller number of the Army's Model 70 rifles also saw combat use by Army snipers; and some were equipped with silencers for covert operations in Southeast Asia . These Model 70 rifles never achieved the status of a standard military weapon; but were used until replaced by the Remington Model 700 series bolt - action rifles which became the basis for the M40 series sniper rifle . </P> <P> One of the reasons the U.S. Marine Corps replaced their Winchester Model 70s was that the post-1964 variants of the Model 70 did not meet U.S. Marines' standards . Despite the introduction of the Remington Model 700 rifle, the pre-1964 Winchester Model 70 was still used by the US Marine Corps' scout / sniper teams during the Vietnam War alongside the Remington Model 700 rifle . The original wood stocks were found to be warping in both rifles after a few years of service and both rifles were given fiberglass stocks to remedy the problem . Existing Model 70s still in service have had their stocks replaced with a McMillan fiberglass stock, such as that found on the Custom Extreme Weather variant . </P> <P> One of the best known U.S. Marine Corps snipers who used the Winchester Model 70 during the Vietnam War was Gunnery Sergeant Carlos Hathcock, who used a Winchester Model 70 sniper rifle chambered in . 30 - 06 . It was this rifle, equipped with a standard 8 × 43 Unertl scope, that Hathcock used to kill a North Vietnamese enemy sniper by shooting him in the eye, through the scope of his Mosin--Nagant rifle . Hathcock's rifle is on display at the Quantico, Virginia Marine Corps Sniper Museum . </P>
