I then took measurements of an AEG cylinder (check me if my measurements are wrong), and I found the diameter to be 24mm and the length to be 72mm. Using the same equation above, I found a cylinder's volume to be 32572 cubic mm. That means a type-0 no hole cylinder has 175% the volume of the longest barrel on the market. This makes me question why bore-ups are necessary, considering their purpose is to increase the cylinder's volume to fit the barrel. However, I understand the entire volume of the cylinder is not used because the piston head and cylinder head take up some room inside the cylinder. I also understand that aeg's are not 100% efficient. This still doesn't justify to me the need for a bore-up cylinder when it's volume is 75% more than the barrel. Cylinder volume should not be an issue even with these considerations.

Go for it then...and when you end up with a 200fps rifle, try a bore up kit.
