are there lowers any good?

Never heard of'em.

Me neither

Link?

There used to be a Champion Arms in Fife, Washington. Any connection?

never heard of'em either. Though I most certainly expect more companies to come online during the shortage.

I'm not sure how long it takes a modern CNC machine to spit out a mess of lowers and uppers but in todays market there has to be some shops looking to add work that are quite capable.

I really would like to see someone start cranking out bolt's, carriers,extractors, gas keys and a few other things. Seems to be a pretty good shortage of complete carriers as everyones using them for rifle and upper builds nowadays.
