Initial testing Great!

I purchased this upper from GM a year and a half ago then had a hip replacement. I'm back to work in the shop. Got an 80% lower milled and put together the lower receiver with an A2 buttstock. Upper and lower fit well. Test fired great! Ejection pattern and cases look good. I need to break it down and do an inspection including a borescope. If all looks good I move on to optics, and a fifth review star.
