Before you go off and post me the thread for the reciever post, its not in there, and the AR sticky, its not there either. Basically I'm asking two questions, is it a good thing, and is it another thing to have break? Basically if I"m not buying a billet, should I get one.

Basically whats up with the secondary set screw?

It allows some adjustment in the trigger.

"set screw located in the pistol grip for trigger preset. This allows a tunable match trigger from a standard GI trigger."

I have 2 Superior Arms lowers, the are as good as any others. The finish isn't as smooth and black as some others but still looks good. The deal with the set screw is to help "eliminate" overtravel. About the same as the ones on some 1911 triggers. It won't give you a "match trigger". Like with my 1911's I don't put those setscrews in.
