ok From the barrel how high dose the scope have to be?

I tried gluing the scope rail on the barrel then clip and screws on the rail
but its still not accurate

so any one with a solution feel free to sugess
thankz

Spudguns are so largely inaccurate that scopes are not useful.

ohh fare enough

but even for a custom made 15.5 mm barrel
for marbles?

i used one on my marble gun and it was fairly accurate at 50m or so, i used a block of wood that was all square and drilled a hole for my barrel to go through and mounted the rail on that.

THe shortest possible. The higher the scope, the bigger the angle between em is needed for a certain distance.

first attach your scope with something that will allow adjustments. due to the quick fall of ammo, youll need to have a range scope which is complicated to make at home, and likely will not resemble what you want. for a marble gun i would just look down outer edge of the barrel.... if you have ever learned about history and the poor performance of musket balls you would know that a scope on a marble gun is useless, unless you use batteries or something that will make some attempt to fly straight.

You could use ammo like dart ammo. That should fly stright.

Thats what zero-ing in for is

Lower is suggested
