  • Patent number: 7127845
    Abstract: A paintball marker comprises a main body 10, a barrel 12 defining a firing axis X-X, and a grip frame assembly including a frame 26 and a trigger 22 pivotably mounted in the frame 26. The trigger has an upper finger engaging portion 50 and a lower finger engaging portion 52 so that it can be operated by two fingers 54, 56. The lower finger engaging portion 52 is curved round so that its finger engaging surface 66 ends in a horizontal part 68. The pivot axis of the trigger is adjustable between a number of positions, one of which is offset to the rear of the finger engaging portions 50, 52 so that the trigger can be operated by pulling downwards on the horizontal part 68 of the finger engaging surface 66.

  • Patent number: 6739322
    Abstract: A paintball feed system (10) comprises flexible detent beams (32a,b) that flex about first and second support points (33,34) such that they allow a paintball (22a) to pass from a hopper (18) into a feed tube (12) leading to a paintball marker's breech (16) under it's own weight when flexing about the first support point (33). The beams (32a,b) are rigid enough, when flexing about the second support pint (34), to prevent the return of the paintball (22a) back into the hopper (18) from the feed tube (12).

  • Patent number: 6474325
    Abstract: A gas regulator, relating in particular to a regulator for a gas or air cylinders, for supplying compressed air to a paintball gun or other compressed air powered projectile firing devices. A micro controller operably associated with the gas regulator is adapted to generate a shots remaining signal by receiving a pressure drop signal from a pressure transducer and a set of shot fired signals corresponding to the gas pressure drop signal. A method is also provided for generating the shots remaining signal using a second gas cylinder temperature signal, a temperature compensated shots remaining calibration constant and a gas regulator input pressure signal.
