Feyachi RDS-22 2 MOA Red Dot Sight Compact Red Dot Scope 1 x 22mm，Selectable with 5 Slots 0.83”Riser Mount

I mounted a pair of these on my Ruger Mark III Target handguns. For the price they are a very functional, quality product. I’ve not had any issues zeroing the product, holding zero or failure to function in any way. I’ve used other more expensive red dot sights and find these to have more options and work just as well. Adjustments worked as needed to obtain the proper sight alignment and the battery compartment easily accessible.

Optic packaging seems to be of less quality than how Feyachi package their off-set flashlight (Feyachi FL11), which is curious or they have that much confidence of the durability of this unit. You decide. Package contents include: Optic Unit P-rail Riser Block Separate rubber-band style dust cover. This optic does not have attached flip-up style covers. Cleaning cloth EXTRA Battery (for when you forget to turn this unit off after utilizing) Instructions Pamphlet (that you will probably not need for anything other than dialing this unit in at the range) Torx and Allen key for mounting and adjusting. end. Overall construction appears durable and solid. Mine had a small chip out of the black coating by the battery/case/on-off dial as seen in the photos but nothing that impacted overall functionality or aesthetic. Mounting process was intuitive and took a couple of minutes to mate the optic to the riser block and then to the P-rail. For this particular review, I paired the Feyachi RDS-22 optic with a Tacticon Falcon V1 Magnifier and they paired quite well with the magnifier unit having its riser shim installed. See photos for alignment. Figured budget with budget for an apples to apples comparison as someone out there might use that combo for their budget build. Red Dot settings are clear and bright considering the price/value realm that we are dealing with. Again, for a budget build, this optic would be tough to beat. As others have mentioned, there is a manufacturing item that creates a strange "bump"at the 5 0-clock position inside of the rear lens. It DOES NOT impair the line of sight or functionality of this unit. Simply some side-effect of the build process. I cannot say what it is or if it can be corrected next build cycle OR if it has any long-term impacts. In short, this red dot optic functions as intended for a great price point out of the box. Clear line-of-sight with an off-set flashlight. Partially questionable packaging. Some noted manufacturing items (2) that do not impact functionality and are just fine tuning for future build cycles. For a budget build or knock-around weapon you could buy multiple of this unit and get the same end-result as much, much more expensive optics. Note: To clarify two points before I end up answering a bunch of buyer questions...: The pic of the optic and yellow background with the red dot illuminated has a red slash through the lens created by the Camera Flash...not something to do with the Feyachi unit. Next, the pic of the mounted optic with the red dot and yellow background...the red dot is off-center due to the angle of the camera. The red dot is centered as with just about every red dot optic out there. It also easily clears the flashlight mounted canted to the right.

Good sight for the money. Mounted on 1970 Winchester Model 94, 30-30, Brightness dial a little tight when first used but has now become louser. Wish it has a on/off button instead of the dial for speed of turning on. The sight is small so the top ejector works without the casing hitting the sight. Went to range to sight in without problems. Very fast target acquisition using both eyes open. Mounted in a few minutes with no rocket science required. Can not speak for battery life, since i am in the habit of putting new batteries in my equipment every time I go into the field.

This review and optic is similar to another budget optic we purchased for testing. Results were identical in a controlled test using the same ammo and mounts. The only difference is we tested in on multiple rifle builds of multiple calibers and it worked well on all builds. Purchased this dot and had low expectations. It was $48 so what’s to expect? As a huge fan of the Romeo series, especially the 5 and MSR, I didn’t think it would compare. First test was a drop test. Dropped four times twice from waist level and twice from chest level. Lens down; once per side. Dot still works. Second test was throw test. We literally threw it like a softball, twice, onto a concrete slab to simulate a weapon drop and slide. Dot continued to work. Third test was the battery. We put the supplied battery in and left it on, on setting 7. Dot still works after 48 hours of continuous on. Fourth test was brightness. 1-5, indoors was to expectations, and 6-10 setting outdoors is more than adequate. Fifth test was mounting. We mounted with UTG .83 riser for absolute co-witness. Mounted perfectly and Perfectly aligned with BUIS for true co-wit. We mounted this optic to a new 7.62x39 AR platform build (AR-47)/5.56/300BLK/350 Legend and test fired it using 850 rounds. The optic was bore sighted first then 5 rounds to center it. We then tested each upper with 100 rounds. We also ran various drills to check for zero with mag dumps, zipper, rapid fire, and at 25-150 yards for accuracy. No issues with zero. No drifting, no shifting, no parallax, no noticeable dot changes. Conclusion: For $48 you can’t beat this near TRS-25 clone. It’s a great range/plinking toy optic and we will be buying a few more. The biggest question for us: Is it life dependable? Short answer is: We don’t know and that is relative. Battery life is undetermined and will depend on battery type, setting, and usage. Also, we are still not sure of long term usage and round count not are we sure of durability. For this test it held up like a premium optic from a more reputable company. For a battle rifle we won’t recommend it. For home defense, you be the judge. Too many unknown variables for duty rifle render it inconclusive and with ample battery changes and testing it could be okay for home defense. Could be. To be far, this is true for all optics no matter the price range. These 5k-50k battery times are realistic but that doesn’t mean it won’t fail if you don’t use a premium battery. All of the major manufacturers have varying warranties and anything can go wrong even with a premium product. For now, on our PDWs and Duty rifles we will use premium optics but for our range toys we will use these. Will will test this same optic on a few other builds and update the review should we incur any issues. Afterwards, this will live on the 350 legend build to try to determine the durability over time.

the attachment clamps will not tighten onto a air rifle. my 177 cal and 22 cal air rifle attachment point both are two narrow for this wide scope to mount to. scope mount is about 9/16"...air rifle mount is about 5/16" and scope mounts cannot clamp down that far. but it sure sems like a fantastic red dot; going to look for one that fits air rifles...i just returned BOTH scopes in ONE BOX TOGETHER and amazon is busy texting me and saying they will refund the ONE item...i realize they dont yet KNOW that BOTH scopes are in the one box; however the chat will not even ALLOW me to tell them this FACT. it just rattles out that it received the BOXED item and will issue refund for ONE scope...it does NOT even open any window and allow me to SAY [text] anything...now i must go thru the hassle of trying to CALL amazon, which is ALWAYS a nightmare getting past a mechanical robot voice to a real person. ugh!

Not too shabby for the price. Clear lens. Metal construction. Not a fan of the riser they use for co-witness. Good enough for the range, though.

I bought the optic for my airsoft M4 when I realized that I could not use my iron sights with my mask on. So, I looked around online, and soon found this as one of the cheapest optics out there. When I bought it, I was slightly suspicious, given that similar products sell for over 50 or even 70 USD. However, the sight not only proved my suspicions misplaced, but also was way better than I had dared hope. It was easy to install onto my M4 platform, and the 20 light settings guaranteed the dot's visibility in all environments. This optic has made target acquisition much easier in the heat of battle, and I can't wait to use it more. I would highly recommend this product for any airsoft or firearms enthusiast who is looking for great quality at a great price.

I saw a review where someone said he tightened down the optic so tight that 10 threads were hanging out and it was still loose....SAME THING IN MY 2ND ONE. I tried it on multiple rails and tightened the heck out of it and it wiggled in all directions. Poorly machined and poor quality control. So I have one that works. And yes, botnally that calls for a 3 star review but I disagree when it comes to items like this. This makes me skeptical of the overall quality control. So I am returning this and will try another brand now. I know this got great reviews. I know my other works well enough (although I'm taking it easy on my Natos so not a ton of shots right now) however I also saw several reviews that had this specific quality control issue. UPDATE: JUST ONE DAY LATER. Clearly there are some machine calibrations needed in China. After I wrote the above review I thought "ya know....your first one was good. The youtube world loves them. Get another." Amazon sent one overnight. The sight itself now fits tight. It does have a ton of threads hanging out though. HOWEVER!!! The riser was not machined properly. I tightened the screw maybe 3 or 4 one quarter turns. And hit a stop. I thought maybe it was a bad angle but I wasn't putting any effort or torque. It was following the threads. So I took the tightening plate off and just tried it without the riser. NOPE! The threads hit a hard stop and won't tighten past maybe one full turn. Maybe a little more. By now I'm done. So I decided to give it hell with a bigger tool. Pretty sure I was about to break the screw or plate. This is bad man. 2 items. 2 machine issues in 2 separate parts? I was honestly going to delete my 1 star review if this one worked..even though my problems seem to mirror other problems. I get it.....there are a lot of awesome reviews. But it seems the valid complaints all match the same issue. So a machine issue on the tightening mechanism on the scope for shipment 1. And a machine issue on the tightening mechanism on the riser. The pictures show how far the screw goes. I have both packages and should maybe combine the 2 parts that work but at this point I don't trust what's inside either.
