5 of 5 Upper plus Nitride BCG, no CH June 21, 2020
Reviewer: Brett A from Fort Mitchell, KY United States  
Ordered the Upper, plus bolt carrier, Used a different charging handle. No damage from shipping. Everything is solid. My first AR, and my first build, handed it to someone more knowledgeable than me and wanted to know what I paid. The fulfillment workers really read the comment, I had a joke and they delivered. I got a Escape from New York picture. Memorial Day sale, plus covid delays and still delivered in a timely manner.

5 of 5 Great Value Upper June 19, 2020
Reviewer: Ryan Helder from NC, United States  
I ordered mine during the height of Covid-19. Their website clearly stated it could take up to 2 weeks before it shipped, but I was pleasantly surprised when it showed up at my door within 5 business days!
So far it seems to be a fantastic high-value upper. The fit and finish is nice. I ordered mine without a BCG or Charging handle included, and opted for an Aero Precision BCG and Radian Raptor LT charging handle, both of which installed without issue. Throw on your favorite iron sights or optic, and you're good to go!

5 of 5 PMA Upper Receiver April 17, 2020
Reviewer: Jason Hinkle from San Antonio, TX  
First time ordering was reading on ammoland.com and followed a link.  Ended up here with a 20% off which was awesome and worked.  I ordered my completed upper on 4/13 and here it is the end of the week.  It was beautifully wrapped and protected 0 damage.  It looks great and I can’t wait to assemble my weapon once the lower comes in.  I will order from here again and I highly recommend this to anyone that is looking to buy.
