Missing parts. - Aero Precision AR15 Upper Parts Kit w/ Ejection Port

Nothing like finally getting a day off from work and finally having the time to finally be able to put your new gun together just to find out that my aero upper parts kit, is missing the c clip and forward assist roll pin. I have emailed op to see if they can just send me the parts so I don't have to bother with sending this kit back and getting a new one.guess that it's a waiting game now.
