So I finally finished my first lower receiver build. Ameetec lower, A2 stock, Stag LPK. This project was both easier and harder than I thought in some respects. The front pivot pin and detent was by far the biggest pain.
Now it's just waiting for the Bushmaster Dissy upper I have at home and she'll be good to go. Odd thing, though. I had one left over detent from the LPK after all was said and done. I performed all the function checks and everything appears fine. Interesting...

My Stag LPK also had a leftover detent pin.  As did my friend's.  

Horraaaaay for Stag!  Cause those damn detents are the first to get lost during installation.
