    I'm in the "iron sights are more tradition than they are necessary" camp. I haven't thrown away any of my Troys, but I'm not ever going to buy another set of irons. I think they're unnecessary vestiges of a completely different era of firearms concept.

    The way I see it, it's like relying on a GPS to not fail, but yet have no basic map reading/land navigation skills to fallback on should you find yourself LLMF. Murphy always has a vote. The added weight of a set of BUIS is negligible, they don't take up a lot of rail-estate, and while you may never use them, it's better to have and not need than to need and not have. You do you. To each their own.

    I don't think there's a down side to having BUIS on a rifle, I just think it's a pointless expenditure of $200. I'd rather use that money to contribute toward a top quality RDS.

    I will have to disagree with you there. Irons, especially the BUIS folding type, are more prone to damage and having their zero changed far more than the quality optics out there.

    The most fragile sighting system you can have are front and rear BUIS as your primary in the flipped up position. One good drop on concrete and those things are DONE at the least your zero is off. Strangely enough, people who shit on the plastic MBUS, those things survive better than any of the metal ones FYI. Anything that locks upwards is automatically ****ed in a drop. Which is why I will NEVER run Troys on any of my rifles ever again.

    So many here espouse redundancy like it is a magic talisman. I'm sure we can all agree that a broken bolt will take an AR out of action more so than an failed RDS. The added weight of a spare bolt (or even a bolt repair kit) is negligible and wont take up any real estate if stowed in your grip...yet I'd wager that hardly anyone keeps one in their rifle. Why is that?

    When modern and affordable RDS featuring 50K hour constant-on battery life that are damn near bulletproof exist in today's market, BUIS are now pretty much useless.

    Point taken but I was mainly referring to battery/power source failure, not being physically broken (power source obviously not applicable to ACOGs, unless it's a 15+ year old Tritium failure!).

    Personally I am a fan of the Troys. You can sometimes find them on sale for under $150.

    I have had cheap optics fail completely, and have also had good optics get moisture, mud or mystery crud on the glass, so I continue to do the belt & suspenders thing by insisting on optic PLUS irons... even if the irons get a bit on the minimalist side.

    I use DD's fixed irons for any carbines equipped with a reflex/RDS, but recently waded into the LPVO kiddie pool and have just installed a set of MBUS Pro flip-ups (they were available right now and I got a deal... time will tell if they were the best option).

    I use Troys on both my personal and work rifles. I like how solid they are, and how similar they are to GI iron sights in both appearance and function (e.g. the rear large and small apertures). I use the SKD version of the rear BUIS that has the small decent pin to lock the adjustment wheel.

    I use MBUS and KAC. Use really just means I mounted and zeroed them. I use the Aimpoint.

    Can’t really give any good use details but the MBUS are quick and easy to deply and lock up. Easy to lower back down. The KAC are low profile.
