What's the recoil in foot-pounds of the M4A1? I figure if I can correctly calculate the recoil of the M4A1, I can use that for the railgun. However, the comparison is fundamentally flawed. A railgun uses high-powered magnets to propel the projectile, making the comparison "apples and oranges", if you will.
