Not my idea, posted ny HOE from
another forum years ago, craftsman user.
See post blowhard mods.
Using my 1.5 m ,16 mm id tube simply wrapped thicker tie wire around muzzle just to test measurments.
EASY to custom tune!
Face forward target 10 m
Use right eye to center on target using right prong tip
Do not move
Do the same with left eye and prong tip on target and adjust to your preferance.
I was able to get the two lined up dead center using anout 9mm out from tube od and Elevation
About 14 mm above.
This was super fast proff of concept only, as
HOE so insightfully posted it works!
Now to make stiff adjustable fiber optic 2 sight bgun system.
Thinking slotted plate with threaded screw eyes.
This should allow ultra fine horizontal and vertical adjustments.
Will mount in vice for ridgid tuning ,first horizontal
Spacing sights, then shoot to find elevation.
I love innovative ideas to improve function,
this idea seems just that.
Will post photos when finished.
I might adjust horiz so at 10 m are just side by side not overlaped.
Of course as said different distances from target will affect sight reference ,interested to
See if can shoot well between 7 and 15 m.
My eyes are spaced 65 mm and 75 from tube center in mouth and these specs will vary person
to person so my first rough estimate measures will give just a starting point.
THX again HOE for idea from craftsman, rip.
Never knew you but you found neat idea.

Horizontal plate with 2 eye screws to hole the fibre optics! Nice! If I were there with you, I will definitely film your design process.

We will never get consistent results on blowguns due to different darts, inconsistent breath volume. A reason blowgunsights were almost never employed. And as you said, even our eye spacing varies greatly, and the different blowgun lengths.

But should work well for 10m range for competitions!

Spent some time using s shot fiber optic sight mounted adjustable plate and height, two prong style as HOE posted.
Prefer just a simple tie!
Live and learn!
