The BREAK, or Bren AK, is a lower for the CZ Bren 2 that accepts AK pattern magazines and uses an AR trigger, grip and safety selector.

  • Steel reinforcements for magazine lockup.
  • Extended magazine release for easy manipulation.
  • Will work with most AK pattern magazines and drums.

The Bren 2 lower is not a serialized part and does not require transfer through an FFL holder.

This part is manufactured from Nylon using a process called Multi Jet Fusion or MJF. The parts are then sandblasted, dyed and shotpeened for a strength and finish that is comparable to injection molded nylon. The part is black throughout.

WARNING: When using a trigger pack that has set screws in the bottom either DO NOT use them or be very careful/observant when tightening them. They will very easily punch through lower!

*Not all AR triggers will function with this lower. The Bren 2 uses a firing pin safety (pictured below) that locks the firing pin in place until the hammer pushes it aside. AR triggers with thinner hammers will not be able to do this resulting in light/no primer strike.

While extensive testing has been done showing that removing the safety will allow you to use any AR trigger, Dan Haga Designs strongly discourages removing any of the firearms safety devices.

Below is a list of known hammer widths. Those listed in green should work fine. Yellow may or may not work. Red likely to not function at all. The cutoff seems to be about .25". Anything above that should work and below that not so much.
