Gees!!! These info are really making me think how much math is involve in making more effective parts, now I know why some stuff cost so freaking much for a piece of metal!

But I have a question here, not sure if it's answered or not(kind of skip here and there). Here goes:

Does a m16 length(509mm?) inner barrel need a cylinder with no port to match that length of barrel?

If so, let say the stock barrel is 6.08mm in diameter, what would happen if I upgrade it to a tightbore(6.03mm) of the same length? Do I need a cylinder with port now because of the smaller air gap between the bb and the barrel?

If so, instead of changing a ported cylinder, would it be the same to increase the length of the barrel to maybe 590mm to match the cylinder??


The next part if you don't get it's fine to skip it, this jsut kind of help me understand the whole thing but with simple number.
The point of this is to make this a simple and easy math, and not use stuff like a lot of symbols and such so hear me out.
Let say my gearbox produce a 10 push force(10PF) with port.
And gear box with no port produce 15 PF.
Let say it only takes 7PF to move the bb and keep it moving.
For every 6 inch it require 1 more PF to continue moving the bb down a 10mm(diameter) barrel.
For every 6 inch it requires .5 PF to continue moving the bb down a 5mm barrel.

So here's some question:
A) Is it true that it require less PF to move a bb through a smaller(in diameter) barrel(10mm to a 5mm)?

B) In this situation(T/F), the perfect length with a ported cylinder and 10mm diameter barrel would be 12"?

C) In this situation(T/F), the perfect length with a ported cylinder and a 5mm diameter barrel would be 36"?

D) Is it true that cylinder with no more produce more PF?

E) I have a non-ported cylinder with a 12" long barrel, does it match? If not what would happen?


Thanks.
F) I have a ported cylinder with a 36" long barrel, does it match? If not what would happen?
