I did not encounter this thing in the campaign, so I decided to try it out in the MP. I really expected it to be a mini-GAUSS rifle, which in a way it was.

But I soon realized how useless this attachment can be, it has a decently low fire rate, 2 rounds per battery, and heavy damage dropoff. This made it just about obsolete except for sniping heads.

However, after seeing the upcoming weapon re-balances, I think this may become useful like its supposed to be.

Do you use this thing?

In SP it's the best gun in the game. I haven't used it much in MP though

I use it with the SCAR with the ACOG scope. it pwns.
