The HDA3 is a modular brace system developed from a collaboration between Haga Defense and A3 Tactical. The HDA3 was designed specifically to integrate seamlessly across dozens of firearm platforms without sacrificing strength or aesthetics to do so. 

The HDA3 fills a footprint that the gun industry has already come to love while providing a level of quality, modularity and durability that has never been offered in a similar package. The HDA3 is designed, manufactured and assembled in the USA. 

FEATURES:

  • Folding Steel Hinge: The HDA3 utilizes a steel hinge assembly, ensuring a strong lockup in the straight and folded position that will not degrade with use. The HDA3 will by default fold to the left-side canted at 3.5 degrees downward. Right-side folding variants will be available at a later date. 
  • Strong Bones: The HDA3 is designed with all metal internals for maximum durability. An aluminum cheek riser button and length adjustment latch both interface with an extruded aluminum spine that ties into the steel hinge. 
  • Adjustment: The HDA3's length can be adjusted in .5" increments between 7 positions. The cheek riser can be used in three positions. In the lowered position, raised .25", or raised .50". Both adjustments can easily be manipulated one-handed.
