What is the warranty on the Tritium for these sights and the manufacture date?
1728592
10 years on the sights loosing its potency!! Had them on all my guns since the 1980's only had to replace once.
1728593
12 years from the date of original manufacturing. However excludes any dim sight.

Leapers/UTG optics have a limited lifetime warranty through the manufacturer. Thanks Pyramyd Air Team

Tritium is on both the front and rear. It is a single dot on the front and dual on the rear. The rear is centered on both left and right of the ghost ring.

Says China. But I'm happy with it and my other Vortex products. I'm the one in ten that has the astigmatism, so I see a cluster of dots instead of a single dot. But its the same with Eotech and other popular red dots or prism type sights to me.

I'm not positive, but I think the size of the front sight depends on the make and model of the gun plus the way the original front sight is installed. Some gunsmiths buy 6-inch tritium rods and cut them to size. Also, the way the original sight is mounted determines whether special machining is necessary. As far as visibility, glow in the dark is about as visible as it gets.

Mine reads 21-26460-02E (first line) 120m Ci3 (like to the third power)H (second line). On the top of the compass it reads Model 3H; Cammenga; NSN 6605-01-196-6971; U.S. I know for sure I have a government model because I have my dads old one to compare against, and its just like how I remember them from when I was in the Corps. The tritium doesn't last forever. His is dated 1981 and though it works fine, it doesn't glow anymore. Mine is dated May 2013.

It's made by Trijicon . I initially replaced the Walther standard factory sights with another brand night sight. The sights worked fine as far as the glow feature was concerned, however the front sight was difficult to properly tighten. I then installed a set of Trijicon sights which work very well and the front sight is properly secured. Completely satisfied with the Trijicons. I have them on several other handguns as well.

If it's a tritium sight you should be able to see it in the dark. That' why their called"night sights". They may be old. The radioactive element lasts about 10 years and .may be dead. I would send them back

Yes, both front and rear sights are made of steel. You can easily rack the slide one handed using the rear sight in an emergency on something if necessary, unlike the stock plastic sights. These are good plane jane solid sights. There is no tritium, hence the low price. The front sight has a brighter dot then the rear sights. There are better sights out there, but for the price these are fine.

Yes, it is front and rear. A smaller vertical blade capsule is on the rear to give you some alignment. I haven't had any issued with the two different holsters that I've used my 30S in. I think you should be fine. I do love these sights, they are fast acquiring and I don't think the tritium is too bright to be distracting or over powering in a night time situation. Good luck. Oh, they are also a breeze to install. Comes with everything you need from tools to loctite.

It looks like a two year warranty. There also a $60 rebate right now so act fast.http://www.eotech-inc.com/warranty-information

Yes, this is the Tritium sight (see product name). The picture is taken from the Front of the sight, not the side that you actually look through. The rear of the sight has the two tritium dots on either side of the aperture.

Although you cannot spot them in the photo shown you can see them if you go to Troy's Web Site. They are not as visible as you may think in the daylight. The front tritium site is more visible to me even with some day light but the rear sights are at their best in near complete darkness. If it says Tritium it is. They are a very good sight. Excellent.

On my Eotech it has the logo on both sides of the sights, I know there were some counterfeit sights that were made in China...soooo buyer beware.

I've has the sight on for about two years. Tritium will stay bright for at least 12-15 years.

Patented in 2004 not made in 2004.Life on them varies. But they come with a 10year warrenty from meprolight they will require smithing from a gun smith for the rear site and the front tolerance is really tight too. They sell alot of these sites so I doubt anyone would have old ones unless they are used

Tritium is a radioactive isotope of hydrogen, and it does not glow in the dark. As it decays slowly into helium, it emits electrons (called beta decay). The inside of the tiny vial in the sight is coated with a phosphor. When the tritium electrons hit the phosphor, the phosphor emits the light; this is called fluorescence. Some extra info: There are many phosphors, but none of them contain phosphorus. They contain various elements such as zinc, copper, sulfur, etc. Different combinations emit different colored light. The tritium has a half-life of about 13 years. Therefore, after 13 years, only half of the tritium in the gun sight will remain. This does not necessarily mean that the sight will be only appear half as bright to your eyes in total darkness; it is possible that it will seem nearly as bright as when you bought it. I can better answer this in 13 years. Sorry for the long answer.
