My review on primary arms/ yhm upper
by Cameron Taylor
Primary arms I have to say hands down you are awesome. I ordered this lower around 8am then at around 11am I had a email saying it shipped WOW!!! Nice job. As for the upper from YHM works amazingly tight fit with my YHM lower.
Yankee Hill Machine Upper Receiver

The upper and lower were shipped together to the FFL is short order. Both units were very well packaged. The fit and finish is fantastic. Very clean, no burrs, blemishes, or crud anywhere. I am 2 hours into the build with no issues. I would highly recommend the receiver set and Primary Arms. I will do business with Primary Arms again.
Solid product for your next build!
Very happy with this purchase. It was purely "plug and play" and totally mil-spec. Great option for any rifle build!
