it sounds like your problem to the T.
If you refer to my OP, this upper ran 100% through 1,000s of rounds with no problems on my LMT lower with BAD. It's not new.
The lower is and has the same H buffer and Springco blue spring as the LMT lower.

“Laws that forbid the carrying of arms disarm only those who are neither inclined nor determined to commit crimes. Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man.” –Thomas Jefferson, quoting 18th century criminologist Cesare Beccaria in “On Crimes and Punishment”, 1764
