ADBP – ATAC DEFENSE BASIC PISTOL 10.5″ Barrel – .300 AAC Caliber – The not so basic “BASIC AR PLUS PISTOL” by ATAC Defense.

  • 5.05bs
  • OAL:  23.3-27.55 inches 
  • Lifetime Limited Warranty

Upgraded Nickel Boron Bolt and Oversized Ambi charging handle are the features that set the basic plus pistol apart from the basic rifle.

Our “basic plus AR pistol” is superior to other “entry level basic AR pistols”.

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”. 

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 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.

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.

    Excellent bang for the buck (pun intended). High quality pistol that just works every time you pull the trigger

    Bought as a truck gun. It is perfect for that task. The only problem, it is so nice I worry about beating it around in the truck lol. Great Product!
