## Questions & Answers

**Q: How do you charge them?**
A: You don’t charge them. They collect available light, and focus it. In the absence of light, you won’t be able to see anything. If you want visible sights in total darkness, look to tritium night sights ($80+), or a thermal scope, which can be pretty pricey.

**Q: what is the height of the center of the peephole from the top of the rail?**
A: Hi，The distance from the sight hole to the top of the rail is 1.34 in.

**Q: have you noticed the precision aperture rear sight is backwards. Meaning the concave should be facing your eye. manufacture has it wrong?**
A: Perhaps that’s just on yours. I install my sights so that they lay forward when not in use.

**Q: Will these fit on Sig Sauer M400 tread?**
A: Yes, they fit the rail system

## Customer Reviews

### ⭐⭐⭐⭐⭐ Cooler Than Your Uncle’s Fishing Stories
*by T***R on October 25, 2024*

I mean, these sights are so sharp they could probably cut through your neighbor’s endless lawn-mowing saga.Let’s talk about installation first—it's easier than assembling IKEA furniture without the instructions (and with way less existential dread). In mere minutes, you’ll have these bad boys mounted, and you’ll be ready to hit the range like a sharpshooter from a Western movie, complete with dramatic music in the background.Now, the fiber optic feature? Absolute game changer! The vibrant red and green dots are so bright they could probably guide a plane in for a landing. I once accidentally aimed at my neighbor’s cat (don’t worry, it was all in good fun), and let me tell you, those dots are so visible you’d think they were designed by NASA. If you’re looking for accuracy, these sights make it feel like you’re firing with laser precision—cue the sound of applause!And let’s not forget about the flip-up mechanism. It’s like having a multi-tool for your firearm! One second you’re in stealth mode with your sights down, and the next, you’re flipping them up like a magician pulling a rabbit out of a hat. Your shooting buddies will be left wondering how you became a tactical wizard overnight!Plus, they’re made durable enough to withstand the rigors of the range or any impromptu backyard shooting competition. I tested them by accidentally knocking my gun off the table (don’t ask), and they emerged unscathed, unlike my ego after that little incident.In conclusion, the Fiber Optic Iron Sights are a must-have for anyone looking to step up their shooting game. With easy installation, bright visibility, and a flip-up feature that’ll impress even the most skeptical gun enthusiasts, you’ll be the star of the range in no time. Just remember to keep your eye on the target and not on your neighbor’s cat!

### ⭐⭐⭐⭐⭐ WOW!!!
*by T***Y on August 31, 2024*

I put these on my Umarex NOTOS until my optics arrive, These work so well.....They will be staying on the gun for back up sights!! The fiber optics are super bright. Adjustment are precise and easy to do!! Well worth the money! They are NOT cheap feeling at all, They are machined aluminum and I'm sure they will last a very long time!

### ⭐⭐⭐⭐ Surprisingly pleased with this budget option.
*by J***H on January 7, 2025*

Solid materials, construction, and low enough profile. 2 things to note for those who struggle with managing expectations:1) The “fiber optic” are merely colored see-through dots of epoxy(or maybe plastic) that the light shines through in the daylight (they do work well and are actually pretty cool and accurately line up as they need to)2) Adjustment ability needed help at least specific to my Radical (this annoyance only dropping 1 star should tell the rest of the story). The top post would only adjust high enough for me to get my zero consistently 1.5 MOA high @ 50 yards. I had to find a 1/4” picatinny riser(lot harder than it sounds) to elevate my back sight to be able to adjust my front post accordingly to get zeroed.
