Well, I took the 556 out for a spin today to sight in the new Sig diopter sights.

Long story short- There is insufficient elevation adjustment on the rear sight. It tops out at approx 6" too low.

While it is possible to raise it up a little bit more, at that point it has darn near come unscrewed, and the drum just wobbles around. It would appear that there is hope of making it work, but it will require taking it apart, which I have been unsuccessful at doing for the last few hours. Not to mention being sure to void the warranty... Shimming the rear sight is a no-go, as it is quite a precise fit with the rail, and would succeed only in deforming the locking plate when it is tightened down. Am sure not going to file down the front sight, either.

The thing is very far from mechanical zero; as is the front sight. The latter required to be almost all the way to the left with the rear sight centered.

^ These are the elevation "stops" v

Another area of interest:

I think that this will be just fine after I file the stops just a smidgen. MIght be a good idea to open up the windage detent elipse a little bit, also.

ETA>
At any rate.. SUCCESS!

After breaking the rear sight down, and very closely examining all the different surfaces that come into play during elevation adjustments, it became obvious that the culprit was that almost non-existant eliptical cutout for the windage detent. This significantly limited the available elevation adjustment. A few minutes with a round file, and the available adjustment area about doubled. [

]

Cleaned it all real well, and greased it up. As measured on my calipers, the 100m aperature now will adjust upward slightly past 1.0" (as measured from the bottom of the sight assembly), which is quite sufficient.

Wow.

I was seriously considering getting these. Please let me know if SIG says anything and what if anything you are able to do to rectify the issue.

Did you replace the front sight also? I believe the diopter is intended to be paired with the hooded front sight, it looks like it sits a little lower than the original flip-up sight.

Sig has sold alot of these sights

Yours is the first for this, as posted above did you get the set, if not that is the problem. That poll you posted really does not show much class, with no details as to your set up you claim the Aroura would have been better. All the reviews I have seen on the Sig diopter set have been positive, in the beginning they misshiped a few with out the front sight, but have corrected those and sent the front sight. If it really is a problem, I'm sure Sig will fix it.

Yep, the hooded front sight that came with the set is indeed installed.

Clutter up someone else's thread with your pointless Sally Sensitivity drivel.

If you want to quote me use the complete thought!

Or are you working for or are a friend of Dereck at aurora and trying to boost his product? Sorry if I hurt your sensitivity, maybe you don't know how to set up a sight and zero it.

Thanks very much for your post.

I was on the fence between the Sig sights and the Aurora and decided to go with the Aurora due to the fact that I like the looks of it better. (I haven't received my shipment yet). The fact that the Sig might have install issues would have pushed me to the Aurora even quicker.

The factory SIG sight looks like cheap junk to me.

You are a poster child for personality disorders.

If you don't have anything useful to add, then bugger off.

I was able to zero both a Aroura and a New Sig Diopter on my Sig 551 and Sig 556...
I would not want to be second guessing you on this.... you are acheiving the "lolliepop" look via the front sight?
For the 551 series, there are three front sights as varients, a normal, a + and - . I have not read anything of the Sig USA requireing the various fronts however...
Have you contacted Sig about it? One plus of using the Sig sight should be some from of technical support should you need it.
Let us know what works please! :?

I just want the truth

Gunny, in your post on the other forum you ask nice and it was explained what you were doing wrong. Why besmirch Sig and boost Aroura because you don't know the sight picture for a diopter. If you had a valid poll posted I would have minded my own business, but you posted a garbage poll, If you needed help there are people here that would have helped. If the set up was truly defective we would have liked to know that too, but that seems to not have been your intent. Airborne Gunny, lol

I had the same problem with mine.

I reckon that we'll be seeing this more and more when spring time rolls around. Not a whole lot of shooting going on in some of the colder parts of the country, not to mention that fact that it is newly released.

The only objects that exist in my universe at that moment of firing are the clear tip of the front sight post; superimposed center-of-mass over the target.

Update on my SIG sights. Sent two e-mails, no response. Called today and they said I have to send my entire rifle in with the sights. Maybe I am over reacting but I think that is really poor customer service.Anyway I won't be buying any more of their sight sets and if I can help it won't ever buy another SIG product.
It sucks cause unless I want to send the rifle in I am stuck with a worthless $250 set of sights.

It is a BUIS on a battle rifle. At 100yds, that's one dead zombie!!!

So guys, what's the answer? Mine will not zero either. They came today and I replaced the old front sight with the one supplied, and I can't see the front sight through my optics. I can't raise the rear sight any higher. Do I need a riser? Or just a quick disconnect to take my eotech off if it dies at the worst moment?

I carry this rifle on duty, and I was very unhappy with the new sights when they were installed.

Frustrated,

Tim

If they are paying the shipping, send it back. $250 is a lot of money to waste.
