I was looking for various parts for my AR build. I found of couple blogs that mentioned Arm or Ally. The big discussion was about the prices they are selling various AR parts for. Some had complained about shipping and contacting the company. Some wonder if the company was legit. I decided to order a Aero Precision upper. With the shipping and taxes I saved 20 dollars. Once it shipped, I received an email giving me a tracking number. My part arrived 3 days later. The package arrived with no damaged. I was very surprised and extremely happy. I didn’t have any issues and the company kept me informed of my shipment. I will order more items from them. If you want to save money, don’t hesitate to order from Arm or Ally.
