Would the peasant railgun be possible in GURPS?

Well, yeah. It assumes D&D rules ignore physics, until at the specific point the player trying to get away with the peasant railgun suddenly wants D&D to have rules for physics, so the railgun does something.

Sorry, nope. It continues to ignore physics forever, because D&D has no physics. It has game rules.
