I found a Troy Industries flip-up rear sight on jtdistributing.com for $135. How does that price compare to other prices?

Not a bad price, though the revamped ARMS #40L that is one of the contenders for the SOPMOD contract looks like a pretty good value if budget is an issue. They have improved the issue where the sight can be knocked down by debris while in the up position.

+1 on the ARMS #40L
Another good choice is the YHM flip-up BUIS. I have one on my rifle, and it works fine for me. It locks in place in the up position, but folds down with minimal directed effort. You shouldn't have any problems with it inadvertantely folding on you. It also flips up with little effort. Oh, it also costs $45 less than the Troy.
BTW, Lobotomy Boy, I'm glad to see you've listened to the advice to get good with your irons and hold off on getting optics. It shows that you're willing to listen and learn. That's a good trait. Besides, you should be able to get an EOTech fairly cheap in the not-too-distant future.

I'll check into those other sights today. I selected Troy because after reading countless BUIS threads on AR15.com my head was spinning and the general consensus that emerged from the chicken-coup-like cacauphony was Troy.
Thanks.
Thanks.

The Troy is definitely a quality rear BUIS and well-designed. I replaced an ARMS #40 with a Troy just last year. You wouldn't be disappointed going that route; but the old ARMS did about 90% of what the Troy did at almost $40 cheaper. If the 40L now locks in the up position, then the practical differences start to get a lot smaller.
IIRC, the main practical differences would be:
1) 40L has small aperture as the default, Troy has CQB aperture as the default
2) ARMS comes with finger adjustable windage knobs (A2) on the left side. Troy has tool-adjustable windage knobs (A1) on the right side.

You can get airsoft knock-offs for +-$35US. They're still aluminum and the same sizes.

But, they'll undoubtedly not handle the same abuse, caused by recoil, that a Tro, LMT, or ARMS will take. Some things, like weapons sights, are not things you should consider to be replaceable with cheap replicas. For a defensive carbine, you want to put the best possible equipment on it that you can afford. It's all a matter of deciding just how much YOUR life is worth.

If you can find them, you might want to check in to the Matech BUIS. This is our standard BUIS for the SOPMOD kits on our M-4s and I really like them personally. You get both windage and elevation on these sights as compared to windage only on a lot of other sights.
FWIW
A couple months ago, I took a two day carbine class using only my BUIS. After the class I decided to switch to the GG&G MAD BUIS. http://www.gggaz.com/products/madbuis.php

The Matech is just dandy as long as you aren't using them in low-light. They only have a small aperture and once the lighting gets below a certain level the aperture cuts down the amount of light you receive to the point that it is difficult to even focus on the front sight.
Since posting that I had a few Troy sights that I might be willing to part with, I have recieved four PMs about buying them.
I first made the offer to Lobotomy Boy and he will get first dibs. What is left at that point will be available if anyone gets back to me about it. I really don't sell stuff very often and really had no intention of selling these sights, but what they heck ?

Is the windage knob protected enough to keep the GG&G MAD from accidentally being moved? That's my big concern about A2 rear sight setups. For a dedicated irons-only rifle, I'd prefer an A1 receiver. Are the MAD peeps same plane?444 said:

I don't know that remains to be seen. But, you need to put a witness mark on the windage knob so you know if it has been moved and if so, you can return it to zero.
"For a dedicated irons-only rifle, I'd prefer an A1 receiver.
I don't think it makes any difference to me. My rifles are not dedicated iron sight rifles. But, if my optic goes down, my BUIS now becomes my primary sighting system. Now we both know that I will never be involved in a long term SHTF senario, but, I want to know that if my optic goes down, I can use my iron sights as my primary sighting system indefinitely and not sacrifice much in the process.
When I took this carbine class, I used a Troy BUIS with a single aperature: the large aperature. I found it very difficult to maintain accuracy at any kind of significant range. I had taken this course twice before: once with an Aimpoint ML2 and once with a TA31F ACOG. With the BUIS, I shot the worst score I have ever fired and struggled to do that. I had to really pay attention to the fundamentals like cheek weld with that large aperature. At 200 yards I was horrible. I believe (or maybe I want to believe) that this wasn't all my poor skills with iron sights. I shoot some matches fairly frequently with iron sights and am usually competitive.
With this GG&G sight, IMO it gives me the advantage of being able to use either aperature with both having the same zero. It is also a very low profile sight which is important when the sight is not deployed. I originally went with the Troy sight because my ARMs #40 sight was too tall when stowed to allow me to mount an ACOG. So, I replaced the ARMs #40 with the Troy.
"The GG&G MAD (Multiple Aperture Device) BUIS (Back Up Iron Sight) was originally developed to fulfill a request from Naval Surface Warfare for a back up iron sight that provided both a large and small aperture on the same plane and would thus be zeroed to the same point of impact. "
