I bought a BCA upper...

For a new BCA, that is fantastic. If you haven't already, put that upper on your bench and make sure everything is tight! Also check around the GB for any major gas leaks. Make sure you clean that barrel thoroughly now that you put some rounds through it and check the BCG, chamber and lugs for metal wickers and loose fragments. You won the lottery on that purchase knowing my own experience with them. Nice shooting!

Thanks...
I did all that as soon as it was delivered...
The only thing I might have to do is get a H2 buffer...I have a H1 in it now and it's throwing the brass out around 1 o'clock...
