Secret melee animation for brute plasma rifle?

My friend and I were messing around with the new forge glitch and we found out that the brute plasma rifle has a different melee animation with a bayonet than without a bayonet.
Here is the brute plasma rifle with the bayonet

and here is the animation without one

What do you guys think? is there supposed to be a brute plasma rifle with a bayonet in the game but it was cut?

The Scale of Soirapt variant of the Brute Plamsa Rifle has a bayonet and that’s where this animation came from.

I’m under the impression this glitch mimics the weapon you chose to be the configuration while the plasma rifle is just a skin. That is just a normal bayonet melee animation I believe. Or it could be that REQ animaton too

The new brute req scale of soirapt has the same animation it does one melee kill maybe that’s why
