A cue stick for billiards sports has a forearm with an elongated inner cavity that is filled with a filling material. The filling material may be cork, or a similar material that is resilient and/or deformable to provide improved dynamic characteristics upon striking a cue ball. The forearm may also include an improved geometric structure at its joint end which connects with the shaft, whereby an outer housing of the forearm has a solid construction at its joint end with a joint collar affixed thereto.
