BEWARE!! Aero Precision was a wonderful manufacturer of AR-15 and AR-10 components to build your own rifle. I have used them in the past, and love the parts I bought. But in the second half of 2024, Aero Precision changed. They charged my credit card immediately, and then didn't ship my products. It has become impossible to talk with their customer service. They act like a company about to fail and go bankrupt, after burning through your money. After THREE MONTHS of unfulfilled promises to ship, I got my bank to forcibly reverse the credit card charges. I bought "in stock" parts in September 2024. AP promised 1-3 week shipping times. I used their chat feature to ask customer service for an updated shipping estimate. It took quite awhile to get a customer service agent, but I finally got one. They didn't know when it would ship specifically, but reiterated that in stock inventory ships within 3 weeks. After a month, the chat feature got impossibly long to wait for. I used their web form, and got an email saying their staff was working on getting me an answer. Multiple web form inquiries never received any answer. I resorted to calling. First, they reduced their telephone hours (closing at 3 pm). Their wait times stretched into 2 to 3 hours. If I called at 12:30 pm, it would become 3 pm and they would hang up. If I called earlier, after 3 hours of waiting they hung up. I did get through on the phone one time. The agent told me that the assembly I ordered was not, actually, in stock; they had most components, but had delayed the order waiting for one final component (a handguard). It was expected to ship about 11 weeks after my order. She offered me a $50 store credit for my trouble, which I took. But you can't use that without ordering something else. I did that, but AP never shipped that part either. They have now removed the customer service chat feature from their website. They don't answer web form inquiries. They don't advertise their phone number, although you get it if you place an order. They don't have an email address. If you go to "Contact Us", there are only articles about their products - there is no way to actually contact them short of showing up at their front door. Finally, in late December 2024, whenever I call, they don't even put me on hold any more. Their phone message simply says, “We are sorry. No one is available to take your call. Please try again later.” No one will be there later, either. Throughout all of this, they continued to send me daily emails teasing great parts, flashy new paint schemes, seasonal discounts, and blemished part discounts. All the emails do is rub salt in the wound of them keeping my money without shipping any parts. Today, they still advertise 3-5 day shipping times (1-2 weeks for FFL items) -- which is not true. I am deeply sad to lose this manufacturer -- but I advise you not to trust them now. They will take your money (charge your credit card), and I fear you will become one of thousands of unpaid creditors when the company is liquidated. If you find Aero Precision components sold by other retailers, I expect they should still be well made components and ship promptly -- until the retailers can't restock AP parts either. :-(
