Are there any American lever action sniper rifles?

Answer 1

A "sniper rifle" is simply a rifle being used for sniping. As for purpose built rifles intended for use by snipers, there aren't any. The lever action would be undesirable for a sniper, who may often have to fire from the prone position, and the tubular magazines common to lever action rifles cannot accommodate modern long range cartridges which use the spitzer bullets. Although some lever action rifles which feed from a box magazine have been made, they are very rare.
