Which classes have access to the BRT7 Burst Fire Gun?

[Urza]

I'm struggling with the H3 challenge involving leveling this gun to 21, I only know of two classes that have access to this gun, and im not succeeding with either.

[Aganazzar]

the scout

[guts' theme (Cut & Looped)]

the gunner

[Mobscene]

As others have said, Scout and Gunner get it.

I was having trouble with it so I just kept restarting the Dive if I couldn't get it as my second weapon.

[Kalir]

It's available to any Gunner, but Recon Scout is also able to use it as it has the Light tag.

[SoleSurvivor]

I know this is probably late, but if you don't get access to it in the first level, I would restart!
