AT3’s instructional videos on every aspect of the AR15 are invaluable. I watched them all on YouTube over the past week, and my first AR15 is being delivered today. I am looking forward to tinkering with my new rifle using AT3’s knowledge base as my guide.

First I wanna say amazing customer service my items arrived really fast and packaged very safely. Second the FDE is a perfect match for Magpul products. I paired my AT3™ FF-ML 10.5″ Complete AR 15 Pistol Upper with Franklin Armory lower with bfs||| trigger .. AMAZING! GOT A FOREVER CUSTOMER HERE AT3!

I've ordered a few times from these guys. Prices are great. Things ship fast. Like next day shipped out. Can't ask for more! Also, their AT3 line of products are legit.

~ David J.

I ordered from AT3 for the first time on Monday and I received my order today (2 days later). When a lot of companies are making excuses for long turnover times, AT3 provides top notch customer service and very fast shipping.
