I think that technically, there's no obvious reason why the railguns shouldn't be able to fire in battroid mode.
However, it's just not very practical to do so, as in Battroid mode the 4 railguns can only point straight up. There is no hinge mechanism like say on the Strike Valk to allow the cannons to hinge downward and fire over the shoulder.
However, it may be possible that in Battroid mode, the railguns could be used as mortars in the indirect fire role .

uh, how about the kick from the rail guns will knock on its ass. Anways, we talking about something where A back flap flips up and apprently thats where the gun mechanism goes, talking about sci fi things realistically is pointlesss, coz at the end of the day it isnt.
Hella koo toy anywayz
But do rail guns have that much of recoil?
