The Remington 513 T is an excellent target rifle. Last manufactured in 1968, good ones are hard to find, since they tend to be well used. They have the long solid barrel, with Redfield micrometer sights that are just excellent. Very accurate, but heavy. Average but good condition available for $400 or so, but good ones cost $1,000.
About $250 if it is in good shape.
350.00 if in fair to good shape.
about 200$ us if its in good shape
