Abstract

An adjustable comb apparatus for firearms involves a base mounted within the stock of a firearm, a pair of servo-clamps adjustably secured within the base, a comb which has a pair of pins which are slidably received by the servo-clamps, and a locking screw which secures the comb at a desired position relative to the firearm stock. The servo-clamps allow the comb to be adjusted simultaneously in a cast direction and in a vertical direction. A single locking screw is rotated to secure the adjustable comb in the desired orientation.
