The lower works perfect with CZ magazine, MagPul pmag, Lancer mags, MFT mags. POF trigger 4.5lb (300rds no problem), strike industry 25* pistol grip. Great products like always.
A lower receiver for the CZ Bren 2 that accepts *AR triggers, grip and selector switches.
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.
Steel reinforced rear mounting tab.
Frustrating mag release lever pin replaced with a screw that threads in through the magwell making installation much easier.
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.
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.
