• wherein a trigger is provided which is manually toggleable by a user, said trigger configured to move a unity bracket controlling flow of compressed gas along said gas path and controlling movement of said door between said open position and said closed position;
• and
• wherein said trigger manually adjusts flow of compressed air through a 3-way valve with compressed air flow from said 3-way valve controlling a position of a ram including a piston traveling within a cylindrical blind bore, said piston of said ram coupled to said unity bracket for control of a position of said door and gas flow along said gas path.

A paint ball marker, comprising in combination:

• a grip;
• a trigger;
• a compressed gas source;
• a firing chamber, said firing chamber being hollow along a substantially linear path between a back plug and a barrel through which a paint ball is fired;
• a gas path extending between said compressed gas source and an entrance into said firing chamber, said gas path including at least one valve thereon, said valve at least partially controlled by said trigger;
• a loading hole in said firing chamber forward of said back plug, said loading hole passing laterally into said firing chamber, said loading hole at least as large as a paint ball to be fired out of said firing chamber;
• and
• said firing chamber adapted to be at least partially open to an exterior of the marker, other than through the barrel, when said back plug is removed.
