I had a couple of TCM barrels made because I absolutley love the round. The guy that built the barrels has spent years doing R&D and he figured it all out. It uses a standard BCG with gas system and is threaded 1/2-28. The gun pictured is a no frills build but the barrel alone is $400 so the price can not be helped. The TCM 9R ammo feeds perfectly in 9mm coverted PMAGS. The regular TCM ammo is a hair too long for the feed ramp on the conversion mag but it could probably be overcome with some modification.
Gun will come as pictured with the red dot(sighted in already) and one converted PMAG.
I also have a 5.7 AR that i am going to let go if that caliber interests you. It uses CMMG magazines not the PS90 style.
