Used - includes trigger, hammer, selector and disconnect with springs. No pins. Retail for the 4 parts is $159. Here are some actual pics and pics from the DPMS website. Will trade for a Surefire 6P or Cold Steel Recon 1 Tanto.
Please note that some work has been done on the trigger for fitting. See pic #3. I have tried this trigger in my Mega lower, RRA lower and DPMS lower and it fits and functions perfectly.
