Aluminum version in the works! Sign up on this page to be notified when available.

A lower receiver for the CZ Bren 2 that accepts *AR triggers, grips, mag releases and selector switches.

  • 7075 Aluminum
  • Will work with both the 762 and 556 versions. 762 requires the use of AR15 762 magazines.
  • The bolt release/hold open control inside of the trigger guard has been removed as it would conflict with AR trigger placement.
  • Factory CZ AR style bolt release/hold open will be reused on the left side.

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

*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, Haga Defense 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.
