FOUND for a used TBAC 223CB 1/2-28 brake that fits the Ultra series, for a 5.56 build. If you have one please PM me with pictures and how "used" it is, thank you.
If no members have an extra one laying around, Boss Firearms has them in stock. I’ve bought a couple extra mounts and two TBAC Ultras from them—zero affiliation with them but were quick and easy to deal with.
