You don't really need it, but you could mount a compensator or brake. The muzzle device is a flash hider.
You could also change the flash hider to a different one.
I thought the device was a "compensator", because that's what my manual calls it in the parts breakdown.
My device looks like all the internet pictures of the Scorpion, so I guess the manual is wrong.
I tried posting a picture of what I have, but can't figure out how since PhotoBucket stopped supporting it.
Don't take me wrong, I definitely can't tell the difference. I just want to make sure of what I have
