I haven't put too many rounds through my Bren 2 with Dan's lower, but from what I can tell, it is better than the factory CZ one! Components install pretty much like any AR lower. The color is a lot closer to the color of the upper and you can install pretty much any AR pistol grip and trigger. I can confirm that the Franklin Armory BSFIII Binary Trigger works flawlessly, albiet the rate of fire is not as quick as when it is installed on an AR with a heavy buffer spring. Maybe someone can come up with a heavier recoil spring for the Bren 2 to speed up the chambering of subsequent rounds ;)
All-in-all this is a really quality product and really takes your Bren 2 to the next level!
