Which flip up rear sight do you think is good (or the best) for a flat top?

Need one and I'm not that sure which way to go, there are lots out there! I'm more into simplicity and durability than gadget factor.

Thanks for advice or links!

I have the Midwest Industries rear sight folding sight (MCT (ERS)). Seems well built to me. Easy to use and very reasonable in price. Haven't had any problems with it.

I just purchased a Knight's 600 meter rear sight. I haven't had a chance to use it, so I don't know how good it is. I seems well built and it looks pretty easy to use. That might be an option if you want the ability to change the elevation on the rear sight instead of the front one.

Ive got KAC 300 meter BUIS on both of my flattop carbines. Zeroed them once, flipped them down and forgot about them. Simple and durable.

I've been happy with my Yankee Hill flip up.

but is anyone using those spring loaded sights from DPMSI have the Mangonel rear flip up sight and am very pleased with it. It is spring loaded in the down position and locks in the up position. I have it positioned to just overhang the rear of the reiver rail, and a quick push of my strong-side thumb brings it to bear. The aperture is sized more for CQB than long range accuracy, but that suits me just fine. I'm using a YHM front, simply because it's sized for mounting on a float rail and not on a gas manifold rail.

I just bought a Yankee Hill #YHM-9680 Flip Rear Sight (http://www.yankeehillmachine.com/store/sights.html) for my 22LR upper and I'm very impressed with it. It sure seems rugged and just as easy to use.

Most of my AR flat tops have the A.R.M.S. #40 (http://www.armsmounts.com/catalog.php?action=110&cat_id=4) though. I put an XS Sight Systems single plane sight (http://www.xssights.com/store/tactical.html) in them and zero at 50 yards. That gives me a 200m zero for both the larger ghost ring and the smaller target/long range aperture. Even though I have red dots on my carbines, I sight using the iron sights a lot more.

i used the GG&G Mad Buis for a while, i really liked it. it had two apetures, kinda like the original rear sights, one big peep and another smaller. and it locked into place. you just rotate the knurled sides, to change the appeture,really hard for me to explain sorry but they are nice. my dad has a arm's #40 bu i really don't like it to much. right now i use this sight because it works great there is one apeture, which is all i need, and with a click you can change the range, aim center mass and you are target. it is really sweet but i do not know the name of it or the company that makes it, but here is a pic!

I use a GG&G MAD rear BUIS. It is simple, provides a nice sight picture, locks in place and serves as a piece of mind if my Eotech every went belly up.

+1 on YHM BUIS, they are very sturdy.

Possum I believe that is a Matech rear sight. Never used one, but they seem like a good design. I've read that the clamp screw is a weak point in the design.

Very happy with my A.R.M.S #40L (low profile). It allows to me to swap out red dots for magnified scopes without any clearance issues.

ar15.com has a great sticky thread that catalogs all of them. when i bought mine, the YHM were half the price of everything else and very solid, although a couple have nicer features, like being adjustable

I've got the same setup on mine.

I like the Troy and ARMS #40L sights with the same-plane aperture. One problem I've had with the elevation-adjustable flip-rear sights is that they usually only have the small aperture and you can have difficulty using that in low light. So I like the same plane large aperture even if I don't use it that often.

I use the arms # 40-L. I haven't had it for all that long, but I really like it.

possum, that is a Matech. I've got one. Like it.

I've used the Matech, GG&G, YHM, Magonel, ARMS #40 & #40L. My main go to gun has the 40L on it.

They all work pretty well as far as I can tell, though I did break a GG&G one once, but that was my fault, and I don't think anything would have survived. I really like the Matech's click adjustment for range. And I'm currently using the 40L because I had one handy in the store when we were building my last rifle out of spare parts. :)

Only one I have ever used is the A.R.M.S. 40L. It has worked good for me.

I have YHM flip ups on my rifle and my wife's carbine. I like it alot, but will admit our guns don't see the major use that some of the competitors and LE on this board use. For us, it was pretty much budgetary. Two YHM flip up sets or one really good rear sight.

Again, for our use, that paper doesn't care. For what it's worth, I tend to shoot the best groups with my favorite AR Iron sighted through the YHM flip up. I even by my ACOG donut of death groups with the irons:o
