I believe this is called the TBAC 30ba. It is a muzzle brake with a 5/8-24 threading for a 30 caliber rifle. It is used but in good use. Cleaned it off as well. It's made for the TBAC suppressors and the outer threads are in good shape.
Originally I wanted a TBAC can so I bought this when I was saving for a suppressor. Then silencerco did a bogo deal so I switched.
