My first post on this forum. I just ordered the PSA M4 MOE Rifle kit! Its my first ar15 and I decided I wanted to build one because 1 its cheaper and 2 it will help me better understand how the gun functions. I'm putting it all on a stripped lower from PSA. It should be here in the next few weeks hopefully (I know their stuff takes a while to ship).  Any tips on assembly that will make it a little easier? I'm going to be super careful so I don't mar up the surface. Also, will it be a good idea to clean off the dry lube that's gonna be in the super receiver(or any other parts), and I should also clean off any packing oil and after assembly relube all moving parts with gun oil?

There are many good videos on the subject on Youtube.   They'll show you step by step how to do it.





There is also downloadable instructions complete with pictures here on this web site.  I forget where to find it, someone will be along shortly to remind us where it is.



ETA:   I found it for you.  http://www.ar15.com/content/guides/assembly/lower/
