Oh and color, and here's a real challenge for you....urban camo the tank and barrel with [white, gray, black] and small brown highlights around the black....solid light gray for tee and endcap.

...Sort of an Arctic camo look. Would really stand out on that big gun.

The blue might not be too visible in the black if it is a dark shade so you would need to use light blue for it to more visable.

if you have access to a lathe and some 1/8" steel, you could just make your own...

Well jrrdw said for me to use a 3 inch one, which would go infront of the sealing face so the sealing face would get pushed through the porting.

But i dont know if that would work because my configuration is not exactly centered so then it may possibly not even seal.

I could, and might, use a 4" washer from mcmaster carr but i dont want it to interfere with the sides of the piston, so would i just go with a 3.75 inch washer?
