What BUIS for a 6920?

[Brianma65]

I just got a 6920 upper and will be joining it to a CC SA 20 lower. I am looking to add a rear sight that will work with the FSP on the 6920. Any recommendations ? Are they all the same spec or do I need a specific type?
Also any recommendations on an optic mount? I do have a Aero precision mount , but not sure if this will work. Will I need a higher mount?
Thanks.

'F' marked FSB should be compatible with every aftermarket BUIS. Magpul MBUS and MBUS pro are good and fold away nicely.

Depends on how rich your blood is. The KAC 0-600 micro sight offers one of the cleanest sight pictures available in my opinion. The magpul MBUS pro would be my next pick.

I'm fond of Troy and the ARMS#40L myself.

I just got the basic magpul mbus, I'll be adding optics also. I figure the magpul mbus will do...
Thanks

They work perfectly well. Ran the same ones for years.
