I picked up a 'complete' lower recently (Mega Gator receiver, strictly for the receiver as it was part of a trade) that was outfitted with Model One Sales 'kit'. Besides the springs being junk, the detent pins were atrocious and the takedown pins, hammer, and trigger were like potmetal (MIM?). The main part for me was the sear...which made me gasp when I took it out. PLEASE spend a few bucks more and get quality parts!

WTF, over? See that 'groove' all the way around...I'm assuming from a poor MIM process:

"Groove" goes all the way around. Check out the contact surface where it grabs the hammer:
