IIRC, Tromix was one of the originators of the 458 Socom, and he's highly regarded in that realm. I just finished a build with a Tromix 450B, and so far I am pleased with it. Only have about 80rds down it right now, but it's showing potential. Mainly working on 225 FTX for plinking, but will hopefully start working on hunting loads soon.
Have heard good things about Gryphon, Bartz, Satern, and BHW. Also heard good things about Franklin, but the rifle length gas system on the 20" barrel can be finicky. There's a few others out there, but haven't really heard anything about them, yet.
