What's your preferred flip up rear sight?

I tend to use fixed rear sights with red dots so my experience with flip-ups is limited. I do rather like the MBUS Pros that came on my Sionics upper though.

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.

Using only highest reliability RDSs (or optics incompatible with irons) I give BUISs very little thought anymore and almost never use them. Almost all of them do an adequate job, some have nuances as mentioned in the thread.

Last several sets I bought were Geisseles, to go on shared guns that might actually use irons, and needed to be stout. Here: https://geissele.com/geissele-buis.html

I have MBUS rears on a couple FSB guns. Not that I really like em. More of a just in case, better than nothing decision. Yes, they are zeroed. At least, I did zero them. No idea really if they are holding well. I guess I should check.

I really like the Dueck Defense RTs on my MWS. Unfortunately they don't work for my 5.56 guns, white light is in the way on one and the LA-5 on the other. I like where I have them (the light and the PEQ) so I ain't moving em.

The LMT back ups are great sights. Hold zero, return to zero when removed and remounted. But WTF do you do with them. If I really need them they are gonna be somewhere in the parts drawer.

So yeah, my back ups are good for pearl clutching but not so much for actual shooting. I have em cause I think I should, kinda like my FSBs. I'm in for good ideas.

My thoughts are similar to Post 12's. My optics are my main sights and that's where I spent more money. I suppose if I was in the mood at the time, I might have shopped for higher-priced BUISights but sometimes I just either want to go to the closest convenient store or order something online with good online feedback/reviews.

Note, I'm not a high-speed builder-type. My initial AR15 was an issued Colt with the solid triangular front sight post and the rear sight on the (removable) carry handle. I think my old department is still using those, but have now made an Eotech optional, but that's after my time there. I don't know what rear sight was used if the officer went with the Eotech option.

On my personal ARs, one (a Springfield-Armory "Saint") has offset Magpul-brand front & rear folding sights (due to having a low power variable optic (Vortex "Razor") mounted, while the other one (a BCM AR-pistol, hopefully soon-to-be SBR) has Springfield-Armory folding sights, taken off from the Springfield-Armory (the BCM currently has a Trijicon MRO mounted).

I suppose my views on BUISights might change should I ever bash them into pieces climbing out of or into a vehicle or other activities.

Here are some sights that have worked very well for me.
KAC
Troy
MBUS
MI

I'll point out that the MI front and rear combat folding sights are great pieces which are also very well priced. I have them or 3 or 4 of my weapons, and would like to chuck them on a few more.
