this is not my question,but is a question of a friend. He does not want to make an account for just one question. He is making a dual chamber pneumatic gun. He question is: should he keep the barrel parallel with the chamber like this

or should he put it up at an angle like this

My friend and I thank you:)

Personal preferance. If you angle it like the second one, you can just strap it to a piece of plywood and fir it for distance shots. If you keep it straight like the first one, you can use it better for damage shots at close range.

Performance is the same either way

First one, definitely!
You could always angle it up using a stand later on.

I would recommend makeing it adjustable but if you dont want to go through the work that would be required do the first one no question about it.
