5 of 5 First Purchase from Pickett's Mill Armory May 18, 2020
Reviewer: T.E.S. from Tucson, AZ United States  
Ok PMA, was looking to build another one. You know how us 2nd Amendment folks are. Came across your upper and heard great things about PMA. Price, Quality and your service. The price was very reasonable, so I bought. Upper has a great Magpul hand guard. The barrel has a clean finish. Everything I was expecting from this part. So connected to another one of my lowers to check for fit. Seamless, fit my lower (different brand) MilSpec for sure. My lower for this build will be done tomorrow. I have my red dot and back up sights ready to put on as well. Will be shooting it this weekend. Shipping was fast and packaged correctly. I would buy again. Giving 5 stars for now, don't think I will be let down after firing.  

Thanks PMA.

5 of 5 Really light weight May 12, 2020
Reviewer: Jeff MUEHLHAUSEN from Eufaula , OK United States  
Just got my upper and added a rise bcg and raptor charging handle.  It all went together in minutes and was smooth firing.  Gun is light enough for my young son to safely fire.
