Red dot did not hold 0 within 5 shots with an sks 7.62/39 rounds. Then after 20 shots it kept turning off after every shot. Everything was installed right and tight. The magnifier was ok.

Magnifier feels really good for the price and is clear enough for me. This issue is that the reflex sight assembly is crooked when mounted on any of my rails not just one. the reticle is also crooked by about 20 degrees so the crosshair looks more like an X. Reached out out customer support to see what they have to say. I would definitely recommend a different sight for the magnifier.

This was a great purchase. The only reason for 4 stars is that the eye relief on the magnifier is very close. Other than that great product.** Edit june 19th 2022. I tried to install on a rifle today but the magnifier does not line up with the red dot when in fully locked position. The magnifier must be unlocked and raised to line up, meaning the magnifier is useless because the slightest bump will move it. I am removing stars because of this fact.***edit 2***Nov. 3rd 2022. I am adding the stars back to this review. I reached out to feyachi and told them of my issue. They immediately sent me a new magnifier and it is dead on. This is a+++ service right here. Don't hesitate to purchase as they will make sure you are happy with it.

watched a couple of reviews on youtube, and read all the reviews on Amazon. boy are they wrong. Put this on my M4 Carbine 5.56/223 until i can save for better quality site.Sited in at 25yds then at 50 yds. these were not horrible. Moved out to 100 yds and there was problem 1. As you can see from the photo this thing will not hold zero at 100yds. it is all over the map. Started out good for about the first 6 shots then got worse. Just to make sure it was not me i moved back to 25 and fifty and shot with iron sites and as you can see my shot groups with iron sites are good. I was going to iron site it at 100 but ran out of ammo.The other issues with this package the magnifier. I was able to get the magnifier to focus on the target or the red dot but could not get both clear together. Also the magnifier would not focus at 5x on either the target or the red dot so 5x was useless. The focus on the magnifier at the front is so touchy, the slightest adjustment brought things out of focus. Another issue with the magnifier is at 1.5x you adjust the focus and get it just right, but each time you adjusted the zoom to a different power you had to play with the focus to get it just right which was a pain considering how touchy it is. and when i say each time i mean you go to 2x from 1.5 you had to adjust, you go from there to 3x another adjust and so on.I would not recommend this optic to anyone.No fault to the seller but the manufacturer failed big time on this design for both the red dot and the magnifier.

Magnifier is fine. Optical on reflex is brutal.. if you gently tap it everything is thrown off. Blurry reticle too. Have not been able to sight it in so I switched to a Tasco red dot.update. contacted customer support and they were quick to resolve and ship a new item to replace the defective. great service

My review: For starters. i installed the combo on and went to the range. Here’s what I found. The red dot is very bright and sharp, I had no issues picking it up in the full sun, the optic mounted tight and securely to my receiver, the weight is manageable, not light as a feather but not heavy either, the finish was typical of a budget optic, the glass on the RED DOT was very sharp, BUT I wish the glass on the MAGNIFIER was sharper~ it left more to be desired. Overall construction seemed very SOLID. There is a little “play” in the magnifier but I have ZERO complaints and didn’t even notice it while shooting however I would prefer it were a more solid spring hinge. It is a push button design, I would like to see a flip design that doesn’t require the push of a button. Setup was medium difficulty level. I had dark shadow in the lower 1/3 of the glass when first mounted so I added a UTG “low” picatinni riser to bring the glass higher above the receiver and that fixed the issue, I liked that they included a hex screw driver to adjust up/down/left/right of magnifier to get proper center alignment of the red dot paired with the magnifier. It would be more convenient if this adjustment function was a “tool~less” design maybe with turning turrets. One thing i found very helpful was to mount the magnifier as far back on the rail as it would go as well as being the focus ring all the way out. This gave me optimum eye relief and viewing. One thing I was disappointed about was the low light transmission, I noticed at dusk it was noticeably dark. My favorite feature of all besides the very bright red dot was the 5x magnification. For this reason I can’t justify spending so much more for anything with less. Overall, I was surprised how much I liked the form and function of this setup. Also, I very much like how it looks. Side by side with optics of higher price, a person would not be able to distinguish a noticeable difference. I’m a world of very expensive things, I’m impressed with the high quality level and low affordable price of this setup.The pro’s:1.) PRICE (every other magnifier I see online is like $300)2.) VERSATILITY: zoom range is 1-5x (way more glass than the others which are normally 3x.Cons:1.) low quality glass2.) poor light transmission at duskI rate this optic a SOLID 8/10 overall. I’m very surprised and pleased with how it preformed. I was going to give it a 4-star Amazon rate but the low price tag compared to what you’re getting raised the value level enough in my mind to give it a low 5-star. I don’t believe you will be disappointed in any way with this product. Personally I had my doubts at first but after running several hundred rounds through it, I loved it more and more. Hopefully in the future Feyachi continues to improve their product and enhance the user experience even more.

There are a lot of things that I enjoy about the products in this combo. I love Feyachi's red dots because they are simple, well constructed, and give you the option of four different reticles to choose from. As I do when testing red dots for airsoft, though, I had to sacrifice it to the BB gods to see if it could withstand being shot by an airsoft gun. The lens did not survive a hit from a CQB legal gas pistol. It did technically deflect the BB, as it did not go all the way through, but the glass was practically shattered as a result. This says absolutely nothing about the build quality and worth of the sight, however, as all red dots will do this for the most part. This does help stress that, when using sights in airsoft, make sure to have a lens protector of some kind!The magnifier was well constructed as well. Watching other review videos on them for a bit of added context, it seems that the M37 improved on some shortcomings that were present in the previous model (M36), which is wonderful to hear. The mount construction is great, and the adjustability of both the sight picture and the focus with the adjustable eye piece are fantastic features. The eye relief is shorter than I expected, being most visible around the 62mm/2.4 inches mark, but I am generally using short dots (low power scopes typically between 1.5-5x) that have eye relief of 4-5inches so I simply needed to adjust from what I was used to. Once I got used to the shorter eye relief, sight acquisition was pretty snappy!Overall, I think for under $150 you can't really beat this combo. Is it a perfect product? Not exactly, but it doesn't have to be. It serves it's purpose well and the construction allows for confident use under most circumstances. Just remember to get a lens protector if using it for airsoft!
