Okay I just ordered a Geisselle SSA Enhanced. Pronounced: "Guys-Lee" or "Guys-Lay" is a strange name, but have good reviews. Yea I've already repaced the BM factory 2 stage temporary with a Mil-Spec 5 lb. pull until the "Guys-lee" trigger assy. Arrives.
Good to know about others having the same issues. I had to replace the receiver tube also.
