The extra holes in the cylinders forward of the piston rack slot you are talking about, would these holes be there to reduce cylinder volume (same as any AEG cylinder matching barrel length to cylinder volume)?

I have a RED cylinder in my PTW (no hole) I get 40fps +/- in my M-4 length barrel with the same RED cylinder spring depending what cylinder I put it in.

The RED cylinder shoots less FPS, due to the fact the cylinder in longer, as the piston starts to move forward it pushes the BB down the barrel, as the BB leaves the barrel I have not reached the full benefit of the piston speed and cylinder pressure.

Seems to me the RED cylinder would be better off in the M-16?

Any one else found the same? any thoughts?
