Sightmark Ultra Shot R-Spec Reflex Sight

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.

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!

Smooth transaction. Just as promised.

You really can’t get a better sight for the price, threw it on my 9mm carbine(Fx9) and it has been great, the toggle switch is a little finicky with some play when switching between reticles, but if you take the extra 3 seconds to line up the reticle it won’t move from there.

This is my go-to dot sight for my AR15. It’s sturdy and accurate, firing the gun does not loosen or knock the sight off zero. The QD makes it easy to mount or remove- handy in case I feel like going full iron sights-but the sight picture is big enough that I can use them with the power off just fine. Being able to choose between red and green dots is a nice feature, although mine are usually just set to green. Having the ability to choose different reticles is fun, and being able to adjust the brightness of the dot makes this sight a great all-around option for quick target acquisition.You could spend a lot more on an Eotech that does the same thing, but why?

I bought this along with another sight for comparison and I decided to go with the Sightmark R-Spec. I put this on my Stribog 9mm and it just seem to really belong there :-)I list the pros and cons below:Pros:- All controls are easy to operate (reticle selector clicks into place for each setting)- Elevation and windage adjustment are easy to operate- Easy to mount (quick release is my preference)- Housing is extremely well built and provides excellent protection for the lensCons:- Maybe a bit expensive for most people (at least in my opinion) so look for good deal- Maybe a bit big for some platforms. (In my case, this maybe a bit oversize for the Stribog but I think it made a really strong statement. So I actually love it! Others may want to consider the size carefully.)- The unit (because of the large size) obstructs the iron sight completely so no absolute co-witness possible unless you attach a different iron sight. You may try 1/3 co-witness.Final thoughts. I believe this is well worth the price even though it exceeds my budget. I'm only using this for my shooting hobby (home defense, range, etc...) so I think this is more than adequate. I did look at cheaper alternative but I think comparing the cost and what I would get, I would choose the Sightmark R-Spec again.Final final thought. There is also the Sightmark Core A-Spec (smaller size) that you could consider if you want something smaller. I actually opted for that at first until I realize I cannot change color (red only) and I cannot select reticle mode (dot only). So if those are not important for you, it maybe a better choice. For me I like the options on the R-Spec.

The Good: Seems well made. Bright reticle for daylight.The bad: Reflections in window from the illumination emitter. Caused annoying lines of reflection in the sight. These were pretty bad actually. Seems this R model has different lens materials from the other models - hence less expensive.I also bought the M model to compare. I like the M. Very clear and no reflections. Recommendation would be not be for this R model but for the others in this line from Sighmark. I think Sightmark is a great company with huge value
