Benchrest rifle

A Jay-Young-built unlimited-class benchrest rifle using a 2-inch-diameter (51 mm) Lilja Precision barrel.

A benchrest rifle, also colloquially called a "rail gun", is a rifle with its barrel and action mechanism built into a machine rest, used mainly for benchrest shooting. The rifle has no proper stock and its base uses adjustable feet to provide a stable position on the bench, and the rifle is finely aimed with horizontal and vertical adjustments built into the rest.
