It occurs to me that my post about the Tromix barrel may be mistaken as a general statement of quality dissing Tromix's products--I want to hasten to add that I would--and have for many years--recommended Tromix products without hesitation as being ideal parts for the foundation of a top-quality build--my 458 socom build using their parts has operated flawlessly, accurately and is one of my favorite builds. It's always possible I messed up the install some how--but I don't think so--and I told Tony I'd eat crow if it turns out it was my bad after all.
