Actually, if you think about it any magnetic delivery system *I.E. Railguns* wouldn't have recoil either. There are no moving parts save for the ammunition.
That isn't why things recoil.
A cannon has no moving parts either. The recoil is the reaction force from the moving projectile, if you push a mass forward at high energies then it pushes back.
Lasers recoiling are another matter as the photons emitted have negligible mass (although a photon gun is a potential drive system for spacecraft) but I'm trying to imagine what the turrets would look like if they didn't (when everything else did) and I don't think they'd look right (nothing to do with the science or the so-called common sense) they'd look like they weren't working properly.

<Snip>Recoil from a gun is caused by the explosion of the powder, not the bullet traveling along the barrel. Guns still kick when there's a blank inside.
The recoil of a blank is due to the mass of hot gasses produced by the detonation accelerating.
When a conventional cartridge is fired a mass of black powder/cordite/whatever propellant is being used is ignited to release chemical energy, this energy is converted into kinetic energy in the movement of the atoms in the gas (heat energy) and directed by the chamber, transfering some of its kinetic energy to the projectile.
If the Projectile and the gasses from a conventional cartridge are accelerated to the same velocity in the same time as an identical mass of railgun projectile then the recoil force will be identical, the only difference is where it is experienced.
Conventional firearms do waste a considerable amount of energy, the entire report of the weapon is wasted energy, the heat built up from friction between the projectile and the barrel and the heat build up from the conversion of chemical energy into kinetic.
Railguns theoretically waste less, friction between the rails and the projectile, heat in the movement of electrons in every electrical component and so forth but while the wasted energy will generate forces those forces are not recoil.

Just re-read the bit you've quoted Akita 
The forces generated by convection from a hot barrel are not recoil, the reaction force generated by accelerating a mass from the barrel/rail of your weapon is.
You're correct in almost every particular... except the arguement you're arguing against
