When I had a set of Troys with the round front sight, I found myself wanting to align the concentric rings of the front sight hood and rear aperture rather than centering the front sight post - my FSP was not centered in the circle formed by the hood, so this resulted in misses. Of course this could be a result of something with my eyes, inexperience at the time, or just me sucking at existence in general, so take it with a grain of salt.Originally Posted by Jay

I am quite familiar with all of these phenomena
I'm in a similar position of looking for a folding front sight to fit behind a X300.
I haven't had the opportunity to shoot this setup, but I did get to handle it. A Troy AR style folding front seemed like it would be uncomfortable because the base of my thumb rested on the wing that protected the sight post. I did get a chance to try the HK style front, but I think it would work better.
Fixed DD. Or invest in my next project... But really, get the fixed DD.
Think for yourself. Question authority.
I just found a set of Troy flip us locally, Hk style front. I bought them just because they were readily available but am still going to explore all options so keep the feedback coming please. The LGS was crazy selling ARs as fast as they could process the forms. I bought my dad one while I still could. They were almost sold out and are one of the largest stocking Colt and S&W LE dealers in the country.
I'm very pleased with the KAC BUIS and use them on my Noveske MK18 upper. Pricey, but solid and well designed. Not sure if you care, but I believe the KAC is most commonly issued with the MK18 (though I'm sure other makes can be found in service).
I've used Troys and they are excellent sights as well. I do like that the KAC sights are designed to fold before they break if subjected to pressure (not that I've broken any BUIS...yet).

VolGrad- I don't know how I missed your buying a DD Mk18 (unless you didn't mention it), but it's been on my "lust list" for a while... I think now may be the time to finally pony up the cash before this craziness gets too far away from us.
Did you order through Clyde's or somewhere else? Bullseye Lawrenceville is literally 4 miles from my door, but I've had better service over the phone from Clyde's the few times I've called than I have face-to-face at Bullseye (unfortunately).
My thinking was the same as yours - general HD weapon. I've got a Bushy M4 right now and it's fine... but with the hope of adding a supressor at some point to a Mk18 and it's the perfect HD setup. Have you seen this recent thread on LF about Mk18's? (http://lightfighter.net/eve/forums/a.../m/27320756073)
I prefer to use fold-down BUIS across the board, Troys specifically. Very tough, if one is at all concerned with them taking a beating with the rest of the gun. If one wants basic fold-downs, I feel that they're worth the price, simply in terms of durability.
I never did like how much of a footprint the rail interface of their front BUIS has. It never interfered with my ability to grip up front in any way that wasn't solved by simply turning the BUIS around to face the other way...
....hell, sometimes my thumb would end up wrapped up OVER the front BUIS, and that never interfered with my sight picture...
...but the rail interface WOULD get in the way of how my light mounted, my ability to change out batteries and the like, be it on a quad rail or a VTAC tube. The button that releases the lock, in particular, was a PITA; the light got in the way of using that readily, and it got in the way of the light. On the basis of "I wanna grip the gun THIS way, across the board, how to set up components to match that...?" swapping out a major component like a forearm, getting a longer one for the sake of a BUIS...? Nah. So, try another front BUIS, says I.
I've had the KAC micros for rear BUIS for some time, mostly just because they're practicaly guaranteed to fit under just about any optic I put on the gun. USMC SysCom bought a buttload of these that ended up going on the M27 IAR, and to put on ARs so that Marines had a BUIS that fit under the RCO (and the RCO eye-relief spacer kits for A4s....), so having installed/handled/zeroed a couple-few hundred of the things...kinda influenced my decision to try them. I have to admit that I like the thought of being able to induce elevation adjustments if it ever came down to it...but that's a like-to-have; I take the "BU" part of "BUIS" seriously.
(On that note, there's nothing wrong with Magpul MBUS, but I don't like how mushy and indistinct the windage adjustments are on the rears, nor the polymer apertures. The fronts...if you put a polymer sight close to the gas block, and that block heats up, they can get a little weird in a hurry. Polymer rail covers don't require a zero, so the slight dimensional changes under heat don't matter; on sights, it does. The Magpuls are a "true" back-up sight because of this, in my mind. Somebody else using them as their primary, though, has ZERO effect on my guns, so no biggie.).
Anyway, I had recent occasion to get a KAC front folder, just for the smaller rail interface. MUCH better, there's nothing getting in the way of putting my light where I need it to be (I know that tape switechs are getting BETTER, but they're stil not GOOD, yet. I refuse to use them for anything other than lazerz.), nor with maintaining it; I realize that this aspect only truy affects what I'm after in terms of configuration. Gotta admit that the narrower front post they sport was a bit of a treat; never used anything but standard FSPs before that, another like-to-have. I also like the fold-before-break part. Overall, worth the extra $$$ to me. One thing withthe KAC rears...the windage knob on some of them will move when you flip them up/down. It's certainly not common, but is something to keep an eye out for; software solution is to witness-mark it and pay attention to it when flipping the sight.
I'd not have any problem going back to Troys at need, though. Still have mine, for the next gun or Just In Case....they're a good pick.
I didn't mention it.
I bought mine at Clyde Armory.
I rarely (almost never) visit LF. I'll check the link out later from home.
I like Troy for the iron sight world. They are as good as anything out there, and better than most.
My hang up with the MagPul sights is that we have seen repeatedly where the sights failed to fully deploy. That will considerably change the zero. If we are going to BUIS's, then I would submit for consideration that a good number of things have already gone wrong, and if I need those BUIS's, I need them in the worst possible way, and I need them to be accurate. Not fully deploying is not going to help my cause any.
A little bit of dirt, mud, or crud can cause them to not only not fully deploy, but also fail to return to a fully deployed position after they partially fold under recoil. If I am going to bother with the time, money, and effort to buy, and install, and zero irons, then I want them working properly. A fixed front is tough to go wrong with, or a fixed rear for that matter. Though, as I mentioned above, I prefer Troy's, and I leave the front sight deployed. Troy has true same plane rear sights, allowing for precise zeroing, but use the larger aperature for combat use without a shift in POI. They also lock in the UP/Deployed position which is where I need them locked, not locked in the non-deployed/DOWN position.
I do not concern myself with co-witness because it does nothing to increase accuracy, actually slows down most people, it clutters my sight picture, and is completely useless when fighting at night. However, I leave my front irons deployed, in the event my optic (T-1 on all but 2 rifles) fails, I can use the T-1 tube as a rough rear aperature and get solid hits out to about 75 yards, buying me some time until I can get rid of the optic altogether, and deploy the rear as well.
As usual.........simply my opinion, and worth exactly what you paid for it. YMMV.
