What's your preferred flip up rear sight?

[tanksoldier]

MBUS for fun guns
MBUS Pro for serious guns

The one gas block height front sight I have is a Midwest Industries and seems fine... but I don't have any of their rear sights.

Real quick now, dont think about it too much - what's your preferred flip up rear sight?
I will add that I'm looking to get one sooner or later.
I'll also add that I really dont like the magpul mbus, but that's just my preference.
I used to have a troy diamond diopter flip rear which was pretty nice, even though I didnt get to use it much before selling the rifle it was on.
Last, I realize that what you like & what you actually use can be 2 different things, so try not to give the question too much thought.

On my 6920, Magpul MBUS. Very inexpensive, easily deployed, can take a beating, and accurate enough for the distances that I would engage with it. On my Noveske Recce, Magpul Pro's because or their low profile and easy windage and elevation adjustments like the MBUS.

MBUS Pros and KAC Micro 200-600M

This, plus the KAC 300m.

Troy for me. But in all honesty I don’t run BUIS anymore, just use my aimpoints.

Anything but Samson. I've never had irons not hold a zero till I had a set of Samsons.
