Feyachi Flip Up Rear Front and Iron Sights Best Backup fits Picatinny & Weaver Rails

Been using these for several years, durable, effective and easy to use.

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.

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 ;)

Don’t rely simply on red dot or reflex sights! These are affordable and arrived in great condition. Easy to install, heavy material, looks and feels great. Quick and easy adjustments.

Plug and play

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!

seems to be well built. QC needs work. On the front sight the threads the mounting screw are almost non-existance. Could not get it to bite. Wadded up some plastic around the screw itself and was able to get it to torque down and set right. Not sure how long it will hold but right now its good. Flips up and looks right.
