I have a Yankee Hill Machine QD adapter and muzzle break for suppressor. It came on my T2 but I swapped out for the kurz kit. Both are new and never installed. The brake is 1/2x28 and threads on the QD adapter are 1 3/8”-24, not sure on compatibility with other things but I believe that pitch is fairly standardized. I’ll ship or meet FTF in Indianapolis.
