My first upper I have built. I have been buying the parts for the past year in preparation of the build. I'm going out tomorrow to see if/how she runs.

Sounds like a definite winner to me! Is that numbered upper a Diemaco? Post some pictures if you can.

Dont forget to have that phantom fixed on there to bring you over 16" or start filling out your form 1's right now................UNDERDOG
