Most Helpful Positive Review Awesome sights!
I’ve read a lot of mixed reviews on meprolights tritium sights and I’ve seen a lot of people saying these sights are not bright enough and are a waste of money. But I still took a chance and bought these flip up sights for my CZ Scorpion Evo 3 S1,and I’m glad I did. These sights are exceptional. The...

Most Helpful Negative Review Overpriced and overrated
I was an idiot and purchased these sights without doing any research. They are essentially the exact same as the magpul MBUS sights, only lesser quality and double the price. These sights don’t even illuminate. Good idea but in reality, all for show. Spend your money on something better and cheaper.

tritium on sights sux

by pineyPower, Verified Owner from NJ, United States Written on May 30, 2025
All in all the flip up sights are great. Mounted tight and snug. I raised the rifle to look down the sights and no tritium glow. Not even a speck. I even tried to leave in sunlight for a full day while at work came home to try the sights again with no such luck.
Pros:
  • Mounting
  • Structure
  • fde on point
Cons:
  • tritium suxs
Best Used for:
  • Gucci builds
Would recommend: No

No glow night sight

by Rj, from NM, United States Written on May 19, 2025
My intentions For these sights were to put on a gun that I was keeping low tech.
The front sight is so dim You can barely see it.The rear four dot pattern has no glow at all. Had high hopes for them but I am completely disappointed. The sights should have never passed quality control.
Pros:
  • None
Cons:
  • poor quality
Best Used for:
  • fishing weight
Would recommend: No

Stripped Screws

by Zach, Verified Owner from ME, United States Written on November 2, 2024
So these sights are basically tritium lamps inside FAB defense polymer flip up sights. I really do like them but the reason I gave them 3 stars is because I bought 2 pairs, so 4 sights, and 3 of the 4 screws stripped when I was tightening them onto the rail. I ended up fabricating my own screw and nut to fit them but that's crazy... I would have been pissed if I paid full price but I got them for almost half price with coupons and sales. In the end I got them to work and they're serviceable but come on, are the screws made of polymer too? That's ridiculous...

Great Iron Sights !

by Dad Cat, Verified Owner from TX, United States Written on November 2, 2024
Man, I grew up on iron sights. Never even touched a scope til I was off into my earier 30's. So I had to get some. These guys fit great, work like they are designed to. Cant complain ! Shipping was fast out the gate. Assembly was super easy. Sight picture is great. Much better than the old rifle sights im used to where its just a v notch and a blade sight up front. Reckon it depends on what ya like. Anyways. Check em out ! There are some videos online showing these things.
