Review: Great Optic For The Right Application: Sightmark Ultra Shot R Spec - Ok, just so you know, this is a reflex optic vs an Eotech which is a holographic sight. It is made in the same country that makes the IPhone and most of the computers. With any optic you really need to think about what you are going to use it for. This optic has zero magnification, it is not a "scope". It is designed for short to intermediate range use and for quick acquisition of a target (snap shooting). Range would be close up out to about 300 yards from a practical standpoint. I used it at a local 100 yard range and it put the rounds from my CZ Scorpion Carbine (9mm) in a circle of about 2 1/2"-3" on a sunny day. The optic is made in the same country as your IPhone, most computers and chips. The build quality is much higher than you would expect compared to what you are paying. The reticles are very clear when you use the optic and light levels properly. I called Eotech to ask about how to use a red dot reticle properly. They said that to use it properly, the reticle should be as low intensity as possible and still see it and that all red dot sights will "bloom" when the setting is too bright for the ambient light level. So, set the light level so you can see the reticle but do not have any "bloom" and it works great. Many people think something is wrong with the sight because they have a "bloom" but it is working properly...just turn down the light intensity. Another important factor to consider is parallax correction. This has a 10yd parallax correction distance meaning the dot will be accurately located on target from about 10yds and beyond. This is good for accuracy with some sights are parallax corrected from 25yd or 50yd. I have an Eotech and this is 90% as good for the average person's application (non-military) and more functional on a day to day basis. I bought the R-Spec because I wanted a quick release that folded in closer to the sight and would not get hung up on clothing etc. Also, I wanted a sight that shuts off in an hour or so and not 12hr and is a bit more water resistant. This sight is about 10% larger than the more basic version but still fits on the gun well...an Eotech 512 is much larger in length as a comparison. The controls are easy to use however unlike some of the very early Sightmark reflex sights, cycling through the light levels takes longer. Early models had a dial that you could go from low to high in a split second. This push button makes you go step by step and going from level 3 to level 10 just takes longer. It works fine but keep that in mind. The way you adjust the quick release lever to be tight to the gun is a bit lame. You get a wrench and it works but I would prefer a non-custom wrench to make adjustments. In fact, I would prefer a non-quick release version. If I want to use the sight on another gun, I'll get a standard allen wrench and just move it. The windage and elevation adjustments are easy to work but it takes an allen wrench which is ok once you make the adjustments. The sight stayed sighted in under rapid fire of about 40 rounds of 9mm. I believe it is rated at 338 Win. Mag. Using this for your standard 5.56 AR and 308 AR should not be a problem. A 12ga with slugs would be a very good test. On conclusion, I would say that this is a very good option for your AR or similar carbine to the CZ Scorpion which is very cool. I considered the Sig Romeo 4, Vortex and a couple others and ended up here due to best value for the things I would typically want in a red dot optic. The Sig Romeo 4 and EOTech and a few other do have some awesome features and will likely be an better option when considering lifetime warranty, longer battery life, ranging reticles and so on. But for the price and the fact that I am not an "operator" who's life depends on 100% durability and performance...this is all I need. I also just did not have the money to get one of the higher options. This optic is right in the "sweet spot" for those who don't want to spend 3x-5x more on a military grade optic and still want a reliable optic for the range, competition or hunting. Bottom line is just go buy one of the Sightmark sights that fits your price point and needs and have fun. If in 3 years it fails, go buy another one and you are still ahead of what you would have spent on some of the more "elite" sights.
Review: great "budget" sight - This is the 2nd of these sights I have purchased, they attach easily to the picatinny rail and are simple to use. Out of the box the sight was pretty dead-on, I like having the option to change from a red dot to the green bullseye style, and even taking the sight off one rifle and putting it on another, it was still dead-on accurate. Great sight for basic use without a ton of money spent.

## Questions & Answers

**Q: I just got mine in and the red is ok but pretty blurry, but the green has a double reticle. Can this be fixed or is it just bad?**
A: It is possible you have astigmatism. The easiest way to check is to take a picture of the reticle turned on, then look at the pic you just took. If it's clear then it's your eyes, if blurry, the unit is bad. Hope this helps.

**Q: What magnifiers will work with this site? I know Sightmark will but would like to know if other brands would work**
A: It is always best for alignment purposes that you stick to the same brand. Unless a third party is testing all combinations of brands and measuring them precisely, no one can say what works with what best. Most brand combinations will be close though.

**Q: What is the purpose for the wire coming out of the battery cap?**
A: It is there so you dont lose the battery cap

**Q: Hows the durability when i comes to a 223 caliber does it stay sighted in after multiple uses?**
A: I have a Sightmark Ultrashot M-spec reflex sight. It has night vision as well on mine and I absolutely love it! I zeroed it in when I first got it, and it still shoots true to this day! I paid $250 for the LQD version, but you can get the FMS for $200. They're worth every penny! I'll never use another sight fot my AR! They're both "Military spec" sights. That's why they're higher, but well worth it. You want have to buy another sight!

*by T***S on June 19, 2025*

The Ultra Shot R-Spec has exceeded my expectations. The reticle is crisp and easy to see in all lighting conditions, and the multiple brightness settings are a nice touch. It’s built like a tank—feels solid and rugged on my rifle. Zeroing was quick and it holds zero perfectly after multiple range trips. The quick-detach mount is convenient and secure. Overall, a reliable and affordable reflex sight for range or tactical use!
