Feyachi Flip Up Iron Sight Front Rear Sight Compatible for Picatinny Rail and Weaver Rail of Rifle, Foldable Sights

I purchased two sets of these; black and khaki. I will write a little about each in a bit.For the price, these are pretty darn good. I have several brands of sights, ranging from one set that was over $100 per sight to (now) this set. Are the expensive sights better? Absolutely! However, compared to the $40-$80 sets I have, these are not far (if not on par) to those sets.What I like:The priceThe 'HK' style front sight, as compared to a typical AR style.They lock in the "up" positionThey do not look, or feel, cheapWhat I don't like:The khaki color of the rear sight aperture on the khaki colored sights.The rear aperture has to be in the precision, or smaller aperture, setting to fold flat.The coating is a little too glossy, I'd prefer that it was more of a matte finish.The windage knob is a bit too easy to move inadvertently.As for my likes, hard to beat the price. These are back-up sights, and for that they are good. If I only had iron sights on my rifle, I would not use these (or most) folding sights. If that is what you are planning, just get a set of fixed sights. The 'HK' style front sight is far better than the typical 'AR' style front sight. The 'HK' style is circular, which is much easier to center in the rear sight aperture over the 'AR' style. Instead of centering the post, you center the circular wings and you end up with more accuracy and consistency. These lock in the up position as compared to others that are spring loaded (which is ok) or don't lock and only rely on a ball detent (not ok). Finally the build quality is good, and very good for the price. If I run into long term quality issues in the future I'll update my review.As for my dislikes, the khaki sight aperture on the rear is a problem. The khaki color makes the rear sight much harder to see in more situations that a black one. I plan on painting the rear sight aperture when I get a chance. The rear sight aperture has to be in the precision postion to fold flat. If I ever have to transition to my iron sights I most likely will want the larger aperture. This is an issue in a lot of the rear sights I have, not just these. The sights have a semi-gloss coating, I'd prefer a matte coating. The windage knob could have a stronger spring in the detent, this would help keep the windage knob from moving from inadvertent movements. If one is mechanically inclined, you could remove the roll pin in the windage knob and replace the spring with something stronger. Two other alternatives would be either a lower profile knob or an A1 style windage adjustment.I will address one other thing I have seen people complain about and that is the front sight adjustment. I have seen that some complain that the front sight is hard to adjust, these are just like every other front sight I have ever used in difficulty to adjust. The nature of the 'AR' style front sight post is the same on all these sights. It does help if you have a sight tool, but that only 'kinda' helps.If you're looking for a budget friendly set of BUIS (Back Up Iron SIghts) then these are a good option.

👍🏼👍🏼 VERY IMPRESSIVE!!Very nice sights and a great price! They look really good. They have a little different look to them, the lines are clean and aesthetically pleasing, not just the normal boring straight square block look. They seem to be very well designed and quality made. They are made of an aluminum alloy NOT PLASTIC and they pivot on two stainless steel ball bearings. They are push-button open (pop-up) but you do not need to push the button to close them. I have to admit that at first I didn't like the idea of them not needing a button to close, I was worried they might close inadvertently if you hit them against something (they haven't yet). However after doing a little Tactical Training with them I feel it's actually a good thing no button is necessary because if they do come in contact with something they just flex or pivot and pop right back into position....unless you SLAM INTO something with a 💩load of force.😜 If you do hit something hard enough to close them you just hit the button and they will open again. Making adjustments for sighting them in is very simple and so far they have held zero without issue. Sight acquisition is quick and easy. They come with the allen wrench needed to mount them to a Picatinny Rail System.I would like to see Feyachi come out with an OFFSET version of these!!I took pics and videos of them in action however my SD card must not be made as well as these Feyachi sights because when I attempted to retrieve them the SD card was EVIDENTLY corrupt!!🤬🤪🤬 I will get more pics and videos and post them soon.I would definitely recommend these to my friends and family.

Overall I like the sight. Good value for the money.As others have noted, the rear sight aperture is installed so that the smaller aperture is what needs to be in use in order for the sight to fold flat. The good news is that this is a 5 minute fix. You will need a 1/16 punch, a hammer, flat head screw driver (or a multi tool), and needle nose pliers (or a multi tool). Read all of these instructions before you start. There are some small parts you need to be aware of so you don’t lose them. It also helps if the sight is installed on a firearm first.1. Use the punch to mostly remove the roll pin in the adjustment knob on the right side of the sight. You don’t, or shouldn’t, remove it completely. Just punch it out enough so that the pin clears the post.2. Be VERY CAREFUL when removing the adjustment knob. Do this in a bag, or over something that can catch small falling and bouncing parts. There are two tiny ball bearings on the back side of the knob. Don’t lose them when you remove the knob.3. Hold the dual aperture in place and use the screw driver to remove the adjustment screw (slot of the screw on the left side of the sight) until the screw is free of the dual aperture. NOTE: there is a larger ball bearing held in place by the dual aperture. Be careful when removing the dual aperture!4. Flip the dual aperture around so that the large aperture is in place when the sight is folded.5. Reassemble the sight by screwing the adjustment screw back into the dual aperture until head of the screw is flush with the left side of the sight.6. Hold the adjustment knob so that the ball bearings are facing up and lower the right side of the sight onto the knob. Line up the hole in the adjustment screw with the roll pin. While holding the knob in place rotate the sight so that the sight is laying on the left side.7. Use the pliers to hold the pin in place and use the hammer to reinstall the pin. A slightly larger punch might help.Voilà! Now the sight will fold flat with the large aperture sight in position when the sight is deployed.I only dropped one of the little ball bearings inside the adjustment knob three times. Fortunately I found them. If I had been smart I would have used a bag.
