hey i am about to make an m16 vortex cap gun, and was wondering how the diameter of the cap relates to Rate Of Fire/ Velocity

i want to go more on the faster rate of fire if there is a difference, so what would the best size be

Since no-one replied, I'll take my chances.

I'm not sure of it, but I could imagine that a larger vortex block/cap has a lower rate of fire as there is less chance of a BB to be at the opening at the right time.
I think it does not matter much in terms of velocity.

3/4" cap with 3/4 pipe stuck through it.

k ty, and the comment above this, i see you were the first to put this idea on this forum so ill take your advice after seeing that convincing p90 you have, i thought it was funny thought that i had unknowingly built one of these with one of those little playdoh containers along time ago that you blow in
