Claim 10:
11. A method comprising:
coupling a barrel having an open end to a pressure vessel configured to contain a compressed gas, wherein the pressure vessel comprises a longitudinal axis, a back end surface that is substantially perpendicular to the longitudinal axis, and a cylindrical sidewall that is parallel to the longitudinal axis;
coupling a valve to the pressure vessel, the valve being configured to release the compressed gas from the pressure vessel into the barrel to launch a projectile from the open end of the barrel; and
coupling a shoulder support to the back end surface of the pressure vessel, the shoulder support being configured to allow a user of the apparatus to actuate the valve while the apparatus is mounted on top of a shoulder of the user,
wherein the shoulder support is parallel to the longitudinal axis of the pressure vessel and perpendicular to the back end surface of the pressure vessel such that, when the apparatus is mounted on top of the user's shoulder, the user's shoulder is in contact with both the shoulder support and the back end surface of the pressure vessel.
