I like a balance of the lowest profile possible combined with the lightest weight possible, combined with the sturdiest design I can get. I also don't like, or need, all the complexity of the A2 sight and do not want to replicate all that needless complexity and weight in a BUIS.
I typically say "Troy for folding, Daniel Defense for fixed, Magpul for cheap". But I recently spent a bit of time (3 days) with a Troy fixed rear because I wanted a same-plane fixed rear sight and really couldn't find another one (there's the XS insert but for some reason I can't recall now I wanted to avoid it). I found the Troy sight very usable and as someone used to their folding sight I took to it very quickly.
Another Troy Junkie here...
I run Troys on three of my weapons right now, the fourth is an A2 w/ fixed carry-handle upper. I really want to try out the new diamond-styled Troys on my newest addition... if I can find one in stock somewhere.
HONESTLY SPEAKING:
In all fairness, my opinion of them isn't of professional standards, as I have not tried any KAC or MI or MBUS, etc. My first setup came with Troys, I liked them a lot, and stuck with what I liked.
That's my only opinion, and yes, I have one set out of three that are used enough to be considered "not-so-tight" anymore, but I wouldn't hesitate to use them if I needed them, and it is the rear-sight aperature only. Mine still locks into the detent, however.
I do also like the look of that chopped carry-handle. Simple, basic, affordable! Thanks for the idea!
Fact of life:
Although the EAGLE may soar proudly through the skies, it is very rare for the Weasel to be sucked into a jet engine.
The top is de-horned so to speak and not sharp but is definitely not radiused or rounded. Easy enough to do if that is your choice.
I do many chopped handles as many cops tend to buy 6920's with handles attached. They often need stupid simple, extremely rugged and stupid cheap. For most cops, splitting hairs on weight from a fixed DD and a chopped handle is not a big difference or factor for them especially given the added cost as they are often strapped for cash. I will often set up the rear for an 50/200 IBZ then with a normal 6/3 setting be right on at 300. This is definitely not a concern for many shooters however but it provides that option.
I do run a lot of Troy sights and our unit employs 65 of them. But with our heavy use and the fact that we run them in the up position, we are finding that the aperture's are getting lose and don't stay positively locked and are easily knocked out of position just from having the rifle slung and banging on gear. They can be so slightly knocked out of position that you hardly notice without pressing on the aperture. But results can be scary when you shoot with them out of position. Definitely did not think of this possibility 4 years ago when we first got them.
Stupid simple and cheap. Arguably the most rugged back up sight you can have. If your into counting calories, your going to get another ounce or two. But it does help that the weight is centered to the rear of the receiver and not out on the barrel somewhere. Some may actually prefer that weight in that area of the rifle. Definitely not trying to convert people to using this method, just making people aware of a simple, cheap and effective way of doing a rear BUIS. Many people have never heard of doing it. It is only an option.![]()

And thats what I love about this place. I can always look for something new to try out for myself...

KAC 600m Micro for me!
One reason I like the DD fixed rear sight is that it uses a wire-type locking thread insert so that it doesn't have to be fixed in place with Loctite. I also like the LaRue mount because it's quick detachable.
At this point in my interest in BUIS's, I'm likely to change my mind.
Are there any folding sights that are QD? Or are there any that use the same locking insert as the DD fixed sight?
I've browsed Bravo Company's catalog mainly, and I would have thought for sure LaRue would make one, but I haven't found one yet.
Since this is for my mid-length, I want the option to mount anything from an Aimpoint to a magnified optical scope, so I want to keep my rear sight options pretty versatile.

I'm almost embarrassed to post I like ARMS #40LP, that said my Troys loosened up on me and went back to my old #40's. Looks like I need to look into KAC? Then again I zero'd mine at the start and use optics anyway, and since I'm not kicking down doors they work fine for me, I just want them "in case" I have a optic failure while out varmiting or in a home defense situation.
AIM Surplus has them in stock for a reasonable price ($119, free shipping) - I just ordered a Troy DOA rear folding sight for my BCM yesterday.
