very fragile front sight, and if you leave the protective front sight hood on... you don't get the bright front sight.

I loved the sight at first but it failed to operate after a few weeks service on a BB pistol.  I guess you need to spend more to get quality

I would NOT recommend this sight. The sight fell apart after about 12 shots from a 55 lb PSE bow. The sight ring is attached with short self tapping screws which goes into fiber, not a good combination. Rather than bother with returning I tapped out the fiber deeper and added longer screws. Seems to work.

Nice sight. As another reviewer said, however, it can use a drop of glue to hold the colored sight in place or it can get knocked loose while cleaning or taking out of the case.

I mounted this on my brand new Ruger 30-06. After 18 rounds the eye piece fell out. I put it back it, but it fell out on each shot afterwards. Would probably be a decent scope for something with less recoil, but definitely not a scope for the larger calibers.

First of all, I'm basing my review on using this sight on his airsoft gun, because I bought it to use on a Ruger 10/22 but with the ammo shortage I thought I'd see how it worked on an airsoft gun first. When I removed the sight from the box I noticed fingerprints on the glass, which made me question quality control. The sight mounted and zeroed in pretty easily, and I got the lock screws set and was ready to go. The on/off switch is somewhat small and inconvenient, but for my use was acceptable. However, during matches the sight was more or less useless, as it kept shifting during play and accurate shots were impossible. I'm actually more comfortable using iron sights than I am this sight, unfortunately.

I know there's a huge difference between airsoft and an actual firearm, but the way this performed with an airsoft rifle makes me really hesitant to use it on my Ruger or on my AR. I'll probably try something else for those.

After finally being able to shoot my AR with this sight installed, I wasn't even through the first mag before the glass fell out and rendered it completely useless. Nice to look at but performance was very bad.

If you buy this, upgrade the sticky tape with 3M auto trim tape, or else they will fall off quickly. With the auto trim tape the sight will break off before the tape lets go.

First off The glass is superb. Good reticle as well....perfect for AR application. Now to the bad part. The focus ring at the rear of the optic is lose in the main tube. The reticle however is in the focal adjustment portion so when that focus is turned or bumped the reticle moves. Thus staying on target is basically impossible. Drop it once and I guarantee the thing would flat out break.

It looks cool, and the scope is O K, but the sight on top is mostly unusable. I got what I bought, but I wish I had bought something else.

Nice optic, with the following caveats.
Pros:  1) Magnifier when in position works as described.
Cons: 1) The action to pull back and flip over is not as intuitive or smooth as the slide to flip type magnifiers. 2) More importantly, when flipping the magnifier over it does not clear most rear sights including Magpul MBUS<a data-hook="product-link-linked" class="a-link-normal" href="/Magpul-Industries-Usa-Mbus-Generation-Ii-Backup-Sights-Front-Rear-Set/dp/B01GDL22O6/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Magpul Industries Usa Mbus Generation Ii Backup Sights Front & Rear Set</a>, Trinity Force<a data-hook="product-link-linked" class="a-link-normal" href="/Trinity-Force-Flip-Up-Iron-Sight-Rear-front-Sight-Mount/dp/B00MJKOK28/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Trinity Force Flip Up Iron Sight Rear/front Sight Mount</a>&nbsp;or TacBro Tactical Flip up&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/NEW-Tactical-Flip-Up-Iron-Sight-Rear-Front-Sight-Mount/dp/B00RRCL3NW/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">NEW Tactical Flip Up Iron Sight Rear/Front Sight Mount</a>

After shooting about 1000 rounds the safety became unreliable.  Sometimes it worked sometimes it wouldn't.  Makes the pistol very unsafe.
  So far I have not found anyone that will repaint it.
  The sights are not adjustabe.  This one shoots an inch low and one and a half inches to the left at twenty feet.

This item can't hold up to the recoil the rear sight folds back on you while you are shooting, and the front sight will not work with a low profile gas block.

So far I've only used the front post since I have yet to find a way to get the factory rear sights out of the XD slide.  That set-up works very well though, makes me wish they sold the front/rear parts individually.

Let me start by saying that, in spite of the laundry list of complaints that will follow, this isn't really a "bad" front sight.  It's just not as good as I would have hoped.

First off, this sight requires minor fitting (or at least mine did).  I had to use a needle file to narrow the portion that is inserted into the hole at the top of the slide.  Nothing major, just a little inconvenient.  So be prepared for that.  The nut that comes with this thing is cheap.  When placed side-by-side with the original OEM nut, it's actually laughable.  The threaded portion is less than half the length.  Unfortunately, it has to be that way due to the light tube; i.e. there's not enough physical material to screw a longer nut into (though one wonders why a shorter light tube couldn't have been used with a full-length nut).  The hex head portion of the nut is also about half as thick as the OEM part, and that's ridiculous when you're trying to tighten it down.

The fiber optic certainly does its job, making the front sight stand out much more prominently than the standard OEM sight, but I've noticed a "quirk".  If you rotate your pistol and hold it in a horizontal position like a gangsta wannabe, the light tube increases in brightness.  Rotate it back into a normal person's alignment and the light tube dims a little bit.  This tells me that the majority of light is entering the tube from the sides; when the pistol is horizontal, the sides are facing the overhead lighting; when the pistol is vertical, the light tube is partially blocked by the top metal.  So there's the Catch-22 for this product: the top metal is supposed to reinforce the sight and protect the light tube better than other fiber optic sights do, but at the same time it restricts the light entering the tube.  That's kind of a bummer.

This front sight is too wide (IMO).  It fills up the entire width of the rear sight notch, so that you have no "white space" on either side of the front sight as you're aligning the sights.  The light tube itself centers nicely, but not the front sight as a whole.  This is the biggest detriment of all (again, IMO).  The light tube is supposed to draw your eye to the front sight, but the light tube shouldn't be the point of focus (the top edge of the front sight is).  With no "white space" on either side of the front sight, alignment becomes more difficult.  Thus, I personally would not recommend this sight to be installed on a pistol you intend to use as a defensive weapon.  Your opinion may vary... use whatever you feel most comfortable with.

The sight comes with three inserts... a red & green light tube and an opaque (non-fiber optic) white tube--plus an installation & removal tool which also doubles as storage space for the two unused tubes that aren't on the pistol.

As I implied earlier, I don't hate this sight.  It's alright.  However, I think with a little more effort you can probably find something better.

By the way, for the record, I'm not using this sight with the standard OEM rear sight.  I installed an LPA adjustable rear sight to go along with this.

The first one of these I received was damaged, Okay no big deal. Send it back and get a new one. The next one received seemed to work okay, so I purchased another for my other AR. After using these scopes on 5 or 6 outings, I took one of the AR's from the safe and noticed the knob for the illuminated range finder reticle was broken off of the scope. So I figured I must have hit another gun putting in or taking it out of the safe, so I ordered another. The next day I am at the range with the 2nd scope I own after 200 rds, I noticed the knob on this one has also come off. I have discovered that the 4 screws that hold the knob on had backed out. So now I have 2 scopes that will work but don't have the illuminated range finder reticle. I would not recommend this scope.

Got these to work on my AR15. I liked the nylon case for the pins. If only appearance were the only factor to consider, it would get 5 stars. When I tried to use the 3/32 pin to remove the front sight, it began bending on my second or third strike from the hammer. Within 6 strikes, it began mushrooming.

So the brass is not strong enough for basic gunsmithing work. Since it has been so long between the time I ordered them and the time I first used them, I have no expectation of a refund so will probably just keep as a reminder of a bad purchase.

Live and learn...
