Aving read the thread on pbnation if what they say is true and there is prior art the would SP take on the U.S Navy in a law suit against them the evidence is there that SP are in the wrong was the company even around then in the 1971 heres the text to do with the Navy inventing the trigger that SP have said they invented :-

Abstract: A pellet firing pneumatic machine gun wherein a toothed wheel carries pels from a hopper and conveyer assembly to a position adjacent one end of a barrel through which the pellets are propelled by an air blast from a solenoid valve, the periodic energization of which is effected by a photo-cell exposed to a light source, wherein the light source is placed on the opposite side of the periphery of the pellet delivering wheel from the photo-cell such that upon rotation of the wheel, the teeth thereof act to interrupt light from the light source falling on the photo-cell. In addition, a pellet slitting device mounted on the other end of the barrel, wherein the device includes adjustable blades which score the skin of dye containing pellets shot from a gun to render the pellets more frangible upon impact.

First Claim: Show all 4 claims
What is claimed is: 1. In a pellet propeller operable from a source of A.C. electrical power and a source of compressed air and including a motor, a toothed wheel adapted to be driven in rotation by said motor for conveying pellets from storage means to a firing position adjacent a barrel, and firing solenoid valve means for releasing a blast of compressed air to fire each pellet, the improvement comprising:
a light source disposed on one side of the periphery of said wheel;
photo-cell means mounted on the opposite side of the periphery of said wheel such that light from said source falling on said photo-cell means is periodically interrupted by teeth of said wheel and said photo-cell provides an electrical output which fluctuates at the frequency of the passing of said teeth; and
circuit means responsive to said fluctuations to effect energization of said solenoid valve means in timed relation to rotation of said wheel.
It says everything in this to disapprove SP
