BUFFS! To H&K railguns

So I had the "luck" of finding one of these things and its matching ammo in my latest playthrough. Well the gun is disappointing really, weak, bulky, fires and extremely rare and uncraftable ammo and requires an Ups, and to add salt to the injury its not even silent as the description implies.

So I decided to turn it into a suppressed high tech sniper rifle, upped the damage to 50 (the same as .30-06 ammo) and made it as silent and added a unique sound effect while at it(which may not be the most adequate, it is supposed to imitate a charging sound and the crack of a bullet breaking the sound barrier if you want to propose one).
