Unique grenade launcher request

[Kevlareater]

Basically, something modded around this, but:

 

1. Remove sight from front

2. Add short-ranged or reflex scope (whichever looks best on this gun)

3. Add drum magazine (would contain 16 grenades)

4. Eliminate arc from projectile and increase its velocity (think of a bullet firing)

5. Long barrel equipped by proxy

 

I hope this doesn't sound like an overpowered weapon.
