I am putting together a stripped upper receiver due to not being able to find a complete upper easily.  What am I missing to compete my first build?  I have a complete lower, BCG, stripped mid length barrel, stripper A2 upper receiver.

I am going to need:

A2 FSB with front sight post, front sight spring, and detent pin.
mid length gas tube
magpul moe mid length handguard unsure what I am going to need to put this on
flash suppressor of some sort with crush washer

Am I forgetting anything?  Thanks guys

I'm in the same position myself on my 1st build.

You're missing:
-gas tube pin (may come with FSB, not sure, I got a PRI rail-gas-block which came with the pin)
-standard handguard spring/ring/retaining ring (MOE handguard will attach there)
-MOE handguard doesn't come with end cap so you need one
-fwd assist and ejection port cover assys
-barrel nut
-flash hider/crush washer
EDIT: - charging handle

I think that's it. Don't be like me and forget the handguard end-cap and have to figure out how to get one without paying $10 shipping somewhere

Shit I am a dummy sorry I have a charging handle, I know I need the forward assist and dust cover kit.  A2 came with the rear sight assembly already.  I feel dumb now. LOL thanks for the help.  I also am going to need a barrel nut correct?
