Railgun shots have both a substance and an energy component. Freedom was able to damage Abyss's aquatic thrusters with the Railguns even though they were at least partially if not completely protected by water. That alone shows it has both, the substance ammunition because it continued despite the water (plus what is known about Railguns in real life, check Wiki if you want) and beam because it damaged Abyss even with Phase Shift.Originally posted by: Barumonk

both railguns are substance guns, which are largely useless against phase shift armor.
I don't think Dual was really inferior, they just had different intentions. For example Dual was the only one of the original Gundams that could use weapons from any of the others. All the beam weapons were hard coded to only work with the Gundam they came with, except Dual was programmed to get around that. Also Dual was supposed to be equipped with a Large Bazooka, but that was taken by the Gold Frame Astray. Here is a segment from MAHQ:Originally posted by: Terracosmo
Then again, Duel was in the beginning an inferior model to the rest - and Strike also have all those different equipment sets to it.
"Rondo escapes from Heliopolis using a large bazooka designed for the GAT-X102 Duel Gundam, but the Gold Frame's right arm is damaged because it is not properly calibrated for use with the bazooka. Rondo jettisons the damaged arm".
