How’s the KAC folding 200-600 rear sight? Worth it as a stand alone iron sight?
Troy or the Daniel Defense sights for me.
KAC 200-600m Micro sights would be my sights of choice.
Otherwise, LMT + CSAT Aperture, and standard FSB.
you would want the only sighting system on the gun to be able to flop over with the brush of a hand or a stiff breath?
I thought you were mr. “hard use, storm the beaches”. 
I just went to irons only on this rifle and I think I am going to keep it that way.
I found I was becoming way to reliant on T1’s so I thought this would be a good setup to get dialed back in with irons only.
I really like the LMT set personally…
My experience is a bit limited but the LMT QD Rear Buis has been a bomb proof sight for me.
I’d with a 16" midlength with a Daniel Defense rear BUIS blue loc-tited on. If SBR I’d go with a BCM 12.5" Kino with a DD BUIS.
Exactly what I was thinking.
Same same, know hold overs or if need longer range w/o knowing hold overs, go with the LMT rear.
This is exactly the setup I had many moons ago before Aimpoints were more common. 16" “standard” profile barrel, A1 rear sight, tritium dot front post.
I don’t know why you’d want a folding front or rear on an “irons only” rifle. Why would you need to fold them, or have the additional expense/complication/failure modes of a folding system on such a gun?
I’ve been shooting a 6920 with only a La Rue LT-103 for almost a year now. I love it, it is extremely solid, has kept its zero excellently, and it is practically impossible to change the settings on it once zeroed. I shot a CSAT course with this BUIS only and things went very well. The only real big limitation was shooting out at 350 yards as the carbine length sight radius was very limiting. And personally I can understand the argument for a fixed rear sight, but the LT 103 is so solid that I don’t know if it would be worth it to go to a much more limiting fixed rear sight/carry handle set up as you may eventually want to put an optic on your rifle.
But if I was to go with irons only, IMHO even more important then the type of rear sight, would be to get as long a sight radius as I can get. In a carbine I’d definitely go with a mid-length gun just for that issue alone, or maybe even a Dissipator type set up, or of course if length isn’t an issue, with a rifle length set up.
Re. the CSAT sight: Based on what I saw when I took the CSAT course the rear sight excels in giving you a “surgical” shooting capability at close range.
When using traditional sights it was nerve racking to aim a few inches high and then have the front post/rifle obscuring a large portion of the target (and this was a stationary target) when shooting hostage drills.
However I didn’t try to run the sights at speed. One guy did mention that it confused him somewhat to use the CSAT sight at speed as he was so used to looking for a traditional large peep sight picture. You will also be forced to use the small aperture unless you flip the sight, and as the sight is designed to be left on the U/small peep setting, when shooting at speed it may require some getting used to.
However, IMHO I think that the CSAT sight is worth it if you go irons only as the prospect of hovering a traditional peep sight holdover shot on a CQ moving target in a hostage type situation is a nightmare. So the surgical capability of the CSAT sight at very close range alone probably makes it worth getting used to it when shooting fast. Not to mention the fact that it will essentially allow you to be very precise from 7-100 yards without ever touching the sight.
I don’t know why you’d want a folding front or rear on an “irons only” rifle.
I’ve been wondering the same thing as well. I’ve seen several people mention folding irons, and I’m simply not seeing the point on a dedicated iron sight rifle.
Well I brought up the KAC 200-600m because of what its called. Was just wondering how great it could be.
Assuming this is a serious response and I’m not missing an inside joke…
While I wouldn’t necessarily pick flip-ups as my first choice for an irons-only rifle, I trust the Troy BUIS I’ve used not to collapse on me short of falling onto the rifle and putting all of my weight directly onto the sights themselves.
That being said, I’m assuming the KAC 200-600m are not of the same sturdiness/construction? I only ask because you listed the upgrade as a bonus for the SR-15 in the other thread. For $200, that seems awfully overpriced to not short of bomb-proof.
LMT or RRA rear stand alone, standard FSB or non folding rail Front.
It has an optic now, but…
I would use the LMT or a similar rear sight if I wanted to shoot past 300.
How’s the Spikes working out? What’s the round count up to now?
Let’s stay on topic. There is a Spike’s thread if you want to discuss Spike’s.
I’m assuming you want the max in accuracy, I’d go with FF rail and a covered micro gas block and a fake FSB all the way out on the barrel by the flash hider to give you a longer sight radius.
I like iron sights personally. I love the simplicity of them and lower profile. I’d go with a standard upper with carry handle (I like the carry handle too) if using just irons… A1 or A2 depending on your preference.
