A second Railgun entry in this database lists a slightly lower damage reading of 25, against the 30 damage of its sibling entry, while every other figure matches: a fire rate of about 30 rounds per minute, a range figure of 500 and a clip of 1. It is listed here at the same community-reported price of $730,000. The two entries most likely reflect two snapshots of the same weapon's data taken at different points, rather than two separate items you can own side by side. Either way, the Railgun plays the same in practice, a single, slow reloading shot that punches through cover and vehicles at a range no other heavy weapon in this data can match. It is bought through the Gun Van's rotating stock, added with the Los Santos Drug Wars update. There is no Mk II version. If you are chasing the Railgun to own one, either entry points to the same weapon in your inventory once bought, so the small damage difference between the two readings makes no practical difference.
Buy it from any Ammu-Nation for $730,000 once you reach rank Minor Turbulence.
