I don’t believe I am breaking Newton’s law.. The momentum is not occuring down the long axis of the ‘barrel’ but between the magnets exerting force imparting momentum inward and the projectile exerting force outward in response. Thus the momentum sum continues to zero itself. Thus my continued response that there is no recoil in the classic sense.

If the forces exerted are symmetrical then the projectile goes nowhere. If the forces are asymmetrical the launcher accepts the inverse of the projectiles acceleration, summing the system to zero. Unless you are using a definition of recoil different than any I have ever seen, the rearward movement of the launching mechanism in response to the acceleration of the projectile is the recoil.
