Well theoretically if you strap a minigun magazine on it it would go 900 RPM but most guns in the old world store around 75 rounds per magazine. The length of a gun is around an AK47 of modern-day
But compared to an old world gun that Velo is used to, this thing is lackluster at best with a 900 Rounds per minute without reloading. Compared to the old world rifle, which can dump out 1800 RPM while having little to no kickback for the user.
