It appears the ad is for two different items. Im not sure if mine is the first or the second(muzzle brake)
There appears to be a tube in the center and no holes I can see through like a modern brake. The vent slots only allow me to see the tube in the center. I also do not have a hex nut on the bottom like the picture but a set screw like in the lower description.
I would like to remove it and clean it as I can see some green corrosion in the vents.
It is interesting, I may have to shoot it the way it is to see if its effective.
Thank you for the help
