An alternate way of using railgun parts :
Place them in a shape like in the picture with the coilgun option and tada, you have a coilgun
The difference between a coilgun and a railgun is that in the coilgun, the power is made by making the bullet accelerating inside the circle, so the longer it spin, the more powerfull it become
And the lenght of the coilgun with define the max power it can reach
To make one you just have to place a loader, four accelerator to set the circle, and one exit
The rest (the railgun-looking circle) is just aesthetic and go on top of the ship, so you can place things Under it, but still explode like a normal railgun if one of the main part is destroyed
I think that will meet the exigence of people wanting more way of using the railgun
