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 firearms.
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.
ATAC Defense Lower Receiver: Our lower receiver starts as 7075 T6 aluminum forging that is final machined to our exact tolerances. Our internal tolerances exceed the mil-spec tolerances for a lower receiver. After inspection, it moves through our in-house magwell broaching process to ensure proper dimensions, and a straight/true magwell. After broaching the lower goes through a vibratory tumbler that utilized ceramic media to deburr the lower. Our lowers are continuously inspected during each step in our process, after tumbling it goes through one more final inspection to insure our quality standards. After passing all inspections, each lower receiver is laser engraved with ambidextrous bullet markings, and ATAC Defense information. Additional, enhanced features of our lower include: threaded bolt catch pin, threaded (captured) rear detent pin and a upper to lower adjustment feature.
ATAC Defense Upper Receiver: Our upper receiver also starts as a 7075 T6 aluminum forging that is machined to exacting tolerances at standards higher than mil-spec. It also has to pass inspection at every machining station that it goes through. It then is tumbled and deburred in a vibratory tumbler using ceramic media. After this point it goes through a final inspection to make sure that it meets the standards we require for our firearm builds. During the machining process we choose to leave the upper receiver lugs slightly over-sized. Utilizing the over-sized lugs, we hand fit each upper and lower receiver to insure a proper tight upper/lower fit without slack or rattle.
ATAC Defense Barrel: Our 4.5" 4150 CrMoV barrel starts life as a true gun barrel steel blank per *Mil-B-1159SE
*MIL-B-11595E, MILITARY SPECIFICATION: BAR, METAL AND BLANKS, STEEL (UNDER 2 INCHES IN DIAMETER) FOR BARRELS OF SMALL ARMS WEAPONS. This specification covers alloys steel, bars and blanks under 2 inches in diameter for use in the manufacture of barrels for small arms.
All ATAC Defense barrels are precision bored and button rifled using a 6-groove rifling at a 1:10 twist rate. Each chamber is cut to match the 9mm caliber. After boring, rifling and chambering, we add a 1/2 x 36 muzzle thread.
ATAC Defense Bolt and Carrier Group: Our bolts are precision machined from
After machining the bolt is vibratory tumbled and deburred. It is then subject to *MPI (magnetic particle inspection) also known as MP to prove that the bolt has no defects or flaws.
*Magnetic particle Inspection (MPI) is a non-destructive testing (NDT) process for detecting surface and shallow subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs when no electric current is passed through the test object, but a magnetic field is applied from an outside source. The magnetic lines of force are perpendicular to the direction of the electric current, which may be either alternating current (AC) or some form of direct current (DC) (rectified AC). The presence of a surface or subsurface discontinuity in the material allows the magnetic flux to leak, since air cannot support as much magnetic field per unit volume as metals.To identify a leak, ferrous particles, either dry or in a wet suspension, are applied to a part. These are attracted to an area of flux leakage and form what is known as an indication, which is evaluated to determine its nature, cause, and course of action, if any.
The carrier is machined from *AISI 8620 alloy steel to full auto profile, then stress relieved, and case hardened (carburized).
Buffer and Spring: ATAC Specific buffer and spring
ATAC Defense Hand Guard: Our free float hand guard is machined from 6061, tumbled and deburred. It features m-loc and qd attachment points. The hand guard is attached to the receiver using a steel barrel nut that has been lathe knurled to lock it in place.
ATAC Defense Trigger: Tuned 3.5lb, single stage drop in trigger (curved or straight). This trigger has no take up, breaks clean and has a short reset.
Magazine Release: Our ambidextrous magazine release features an oversized button.
Safety: We utilize a 90 degree, ambidextrous safety made from 4140. It has switchable levers (short and long) so you can choose your desired shooting hand.
Bolt Release: The bolt release in our enhanced pistol is oversized. Our oversized bolt release is fast and easy to find, which helps you get the firearm going again quickly after a magazine change.
Charging Handle: Our ambidextrous oversized charging handle is machined from 6061 T6 aluminum. We chose this handle specifically to make charging the firearm faster and easier, even with optics.
ATAC Defense Compensator: We utilize a forward facing compensator.
Grip: MFT Engage Grip
Pistol Brace: Maxim Defense PDW Brace
