At ATAC Defense: quality, reliability, accuracy and fit/finish are our greatest concerns.
We believe in holding a quality level that is far above “mil-spec”. All of our components are hand picked and tested by the marksmen that design our rifles.

Our upper and lower receivers are machined “in-house”. We perform this critical task ourselves so we can insure proper fitment, without slack and rattle.

Each ATAC Defense firearm is hand assembled with out inspected, tested, and approved components.

After assembly, each firearm goes through a test fire session and is re-inspected. Each firearm must pass our final inspection before it can be shipped to the customer.

This product can only be shipped to a valid FFL holder.
When ordering, please enter your FFL’s address into the shipping field. Include their contact email or phone number in the notes field so we can exchange FFL’s.

    Very nice fit, finish, and features. Functions perfect on 5.56 and 223. Keep up the quality!

  11. Clifton

    I own a few “high end” AR15s. Your guys rifles are every bit of the rifle they are, and in some cases more. High end fit, finish, and reliability without paying for a name. Keep fighting the good fight.

  12. Al

    Shipping was fast, within 24 hours. Fit and finish were very nice. I didn”t notice any machine marks. Upper and lower tight. Functionally perfect with a mix of ammo it fed and fired flawlessly. Accuracy with a MRO was spot on so far. I did a slow break in by cleaning between each of the first 10 rounds then dialed in the sight. Later tried some quality factory rounds and it made me smile. I can’t wait to match some ammo to the rifle for accuracy.
    Very good experience start to finish.
