Feyachi Flip Up Rear Front and Iron Sights Best Backup fits Picatinny Rails with Tool

The last set of BUIS I had wouldn't zero in properly, especially at 25 yards. They were 45-degree offset BUIS that weren't made by Feyachi. I was so impressed with the inexpensive reflex red dot sights I bought from them that I decided to give their top rail BUIS a try. I'm glad I did. Mechanical zero on these sights were only 2 inches low at 25 meters and the windage was dead on. One click adjustment on the front sight post put me right where I needed to be. The final group could have been tighter but I was feeding through the ejection port because of a FGC problem I was having. That made me have to move my head and everything between shots but it still ended up being a 1" group. the mechanical zero group that was magazine fed was less than 1/2". The front sight was a little stiff at first but after breaking it in with a front sight tool it clicks up and down just like it's supposed to. The HK style front sight is awesome, so much better than the classic style, so much easier to line it up quickly. All the adjustments have positive, crisp clicks and both sights lock cleanly into place. The rear sights have white line ticks so you can be absolutely sure when you have mechanical zero. The sights sit at a standard 2.6" above the center bore line, for co-witnessing. All-in-all, these are excellent BUIS, especially for their price point. The construction is durable and the rear sight peeps have a ball bearing under them to ensure a clean transition from the large aperture to your small peep. That ball bearing is always a good sign that the sights are well constructed. As far as BUIS go, you won't find a better sight until you start getting rear sights that have an elevation adjustment You're talking KAC territory and you're talking >$100 per sight. These are about the best bang for your buck when you're starting out.

Let me start by saying that upon receiving my sights this product is very well packaged, it even comes with the Allen key necessary for installation! Opening the box you’ll find the two sights individually packaged in their own little bags along with said Allen key. As soon as you feel the sight in your hand I promise you will be amazed as they feel absolutely solid, and robust. Installing them on your firearm is exceedingly easy, and they fit perfectly. The quality of work that went into designing and producing these is very apparent! Most would assume that no good iron sights can be purchased for such a low price, but let me tell you that these don’t simply look great but they serve their intended purpose exceedingly well. They were even zeroed straight out of the box! Now of course being zeroing will be different on each individual firearm I simply got lucky, and my particular firearm fire exactly where these sights were pointing out of the box. So I took these to the range to test them out, zero them (that’s how I found they were zeroed from the box), see if they withstood recoil (they do from a .223/5.56), and I was thoroughly impressed. The only thing most would see as a downside is they must be manually flipped up(no spring assisted pop-up) and to flip down press the spring sealed button and folded down. However they are very easy to flip up by hand, it can be done extremely quick, and they have enough retention to not fold up when not needed, when transporting, or when carrying the rifle on a sling. I did not see the lack of the spring assist as a downside because once again they are easy to deploy by hand, and can be done so very quickly. These sights also do co-witness perfectly. Overall these are not only an AMAZING value for the price, but I would go so far as to say that they are an AMAZING choice for iron sights regardless of price point or budget range! You get way more than what you pay for, and in today’s market that is a genuine surprise! I would recommend these to anybody and everybody!

As with all things firearms -- you get what you pay for. The Feyachi BUIS are undoubtedly better than nothing on a rifle but aren't manufactured to tight tolerances or for abuse. On a quality set of iron sights, the rear peep doesn't need to move much from center to be zeroed, if at all. On the Feyachi, the actual zero for my rifle required right windage beyond what I would expect. But did they get zeroed? Yes. In terms of the sight picture, I would say it is fair. The front sight post is thinner than I would like & doesn't provide much to focus on for quick targeting. The farthest I was able to accurately use the Feyachi BUIS was 50 yards, as after that the front sight post is difficult to put on target. As for the spring-loaded flipping up/down, the action is very crisp & affirmatively locks into place. Installing the set onto a rifle is as easy as could be expected with no weird issues. I appreciate that the sights include an Allen key so I didn't have to spend time finding the right size. I give a 4-star rating because they're perfect for the price & only fall short on some details. If you don't want to spent $100 on irons for your airsoft rifle, this is a fantastic option. As long as they're handled delicately I'm sure the Feyachi BUIS will last a long time. The metal feels solid but I suspect a single rough hit would put them out of commission. If you're serious about a quality set of irons for your rifle, save up for an industry-standard set that's built for precision in a dynamic environment. I'm going to keep this set because for only $22 it's a fun thing to mess around with! When they die, they die ;)

Can’t be beaten for the price. Easy to adjust and they hold zero well. If I wanted to nitpick, the release buttons are thin and a little flimsy. But these are really great for what they cost and I’ll buy more I’m sure.

Great lil sights

I wasn't expecting much out of these for the price but I was pleasantly surprised when i got them. They feel nice and solid. The windage has nice audible clicks, the adjustment know is a bit wobbly but adequately secure. The lock-up on opening and closing the sights is solid. It locks into the grooves with stainless ball bearings. You have 2 size apertures and they are nice and lightweight aluminum. I honestly can't find anything to complain about with these.

I bought this to replace my red dot that was on my gun. The flip up sight is decent for the price but does seem a little cheap in your hand. It did come with the tools and instructions to install it. It is fairly easy to get dialed in after some time. I like the size of the sights being that they are not too small and the other one is not too big. Definitely worth the money!

Manual flip up and locks in place, push button manual flip down. Update: I ordered a second set. The second was built different then the first. The second had visible ball bearings and was loose when flipped up. The second front sight would not flip down after probably 10 cycles. The push button would not push in. Returned. The first set I ordered did not have the ball bearings and locks when flipped up, no wobble. The first set still works.

Mounted these sights to my 9mm carbine and was surprised to find they lined up perfectly with the RS-30 red-dot I bought from this same vendor. I used these sights to initially set the red-dot and (hah!), they were hitting the 50m target right where I was aiming. Build quality is quite good, the sights lock into position really well and the release works good - they lay pretty flat but I left them up even with the red-dot turned on as they all line up perfectly. Tried combining the front only with the red-dot (works great), and then the rear-sight only with the red-dot (seemed a bit too weird). Even with the red-dot turned off, had no trouble sighting through it using just the fixed sights. Was able to hit the 100m target consistently, but that was pushing the limits of my old eyes and my groupings weren't that great - no fault of the sights, younger eyes would have done better. Might try their low power scope to help with the further targets - was impressed with the quality and functionality of both the fixed sights and the red-dot from these guys.

These seem like really durable and well built sights! I did have a little issue with a missing piece, but was in contact with the seller and they're correcting the problem for me. Otherwise I'm completely satisfied with this product, easy to install and use (Allan wrench included!).

Good sights, picture is good. Mount well, solid. not sure of the accuracy. But sights could be better. Will get the job done fine. but not as nice as higher end ones.

Hold well easy to adjust like the folding locks work well and even after moving several times the still hold zero

Solid pieces. Lock in place firmly, not very easy to flip back down though.
