Claim:
A paint ball projectile marker comprising: a bolt chamber and barrel through which a projectile is received and expelled; a bolt in said bolt chamber sealably reciprocable between a first rearward reset position to accept said projectile into said bolt chamber to a second forward firing position wherein said projectile is expelled forwardly from said barrel by pressurized gas; a hammer chamber connected to and parallel to said bolt chamber; means connecting said bolt and a hammer assembly for simultaneous movement; said hammer assembly comprising: a hammer body reciprocable in said hammer chamber from said reset position to said firing position, said hammer body including a sear lug; a reset rod, a forward head of said reset rod being axially and reciprocably retained in an opening in said hammer body, a rearward end of said reset rod being affixed to said means connecting said bolt and hammer; a hammer spring normally biasing said hammer body towards said firing position; means to supply projectiles into said bolt chamber in said reset position; a handle and trigger assembly, said trigger including a pivotal sear releasably connected to said sear lug to retain said hammer body in said reset position against said hammer spring bias; means to supply pressurized gas ultimately to said bolt chamber via a control valve positioned forwardly of said hammer body, said control valve comprising a valve pin normally spring biased to close said valve, said valve pin extending rearwardly into said hammer chamber in said reset position, whereby said hammer body when released will strike said valve pin to open said valve and supply said pressurized gas to said bolt chamber to expel said paint ball projectile; and means timed to connect with said pressurized gas to force a connected assembly of said bolt, said means connecting said bolt and a hammer, said reset rod and said hammer body to said reset position.
