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.

Each ATAC Defense firearm is hand assembled with our 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.
