Our Story

It started when I bought my first AR-15. While shopping for my first AR, I struggled to find reasonably-priced parts and good information for beginners.

So - I started AT3 Tactical in 2013, with the goals of providing quality parts, friendly service, helpful content, and great prices.

In the early days, it was just me - working from my basement, answering the phones, and shipping out orders. We’ve grown quite a bit since then, and we’ve served over 100,000 customers and counting! But we still strive to provide that same level of personal service that we’ve had since the beginning.

I appreciate you taking the time to read about our company, and I look forward to the chance to earn your business.
