VOTATU V2 Fiber Optic Iron Sights, Flip Up Front and Rear Backup Sights with Green Red Fiber Optics Dots, Tool-Free Adjustable Front Sight Rapid Transition

Excellent quality, especially for the price. Very positive spring action. Solid grip on the pic rail. I have not sighted them in yet, but it seems like they have sufficient adjustment. So far the only negative I see is that the fiber optic does not pick up very much light. Still, it’s easy enough to see the front post. I especially appreciate the two-size rear aperture that easily swaps at a press.I installed these on a 9 mm carbine as a back-up to an electronic red dot sight. They pop up hard and fast at an easy press so I think they function really well in that role.Great value. Absolutely recommend.

I bought these as backup sights for a rifle. They became primary and they hold zero and after several uses, still work well. Good option if you can't afford the high priced sights

Very nice iron sights for the price. Fiber optic is clearly visible during the day, at night it disappears. Couple it with a flashlight and you are good to go.

I was Leary about these because the last set that looked good where garbage, these are well built and seem like excellent quality sights

So many good reviews, and for the price, it's a great sight. The spring loaded flip up is positive and very good functioning. However, the front sight post doesn't stay put; it rotates on its own. It's not loose, but rotates putting the fiber optic sideways, then correct, then sideways every time I shoot on a 9mm AR. Then in less than 30 rounds or so with the rear sight down, it flipped up on its own and wouldn't go down. I found that the nut holding the rear flip up/down push pin fell out. I was able to put it back on again, but found that it was getting loose very quickly before the box of 50 rounds were done. I suppose I can put some locktite on it, but.... Definitely not trusting my life on these cheap build quality sights. It would be good for airsoft or air guns.Edit 11/7/24: Votatu reached out and asked if I would give them another try. So I did and found this copy to be solid. The tiny allen screw holding the front post was locked in so the front post did not move this time. I tested it again by loosening the set screw, changing front post elevation, then locking in again, rinse and repeat. It held up to about a dozen trials. The rear sight held up great this time after 1000 rounds. The nut stayed put and it doesn't appear they put any locktite on it, but then I didn't take it apart to check. So perhaps the first one I got was either a bad one or someone tinkered with it and returned it before me. The fiber optics. didn't do much in an indoor range, and I didn't try it outdoors, but I wasn't too fond of it as my eye just automatically goes to the top of the post. Votatu sights held zero and shot as well as a red dot at indoor distances. I would give it 4 stars on design and function, but their customer service earned the fifth star.

Bought these as an addition to a build. Seem to be well built and they don’t flop around when up

Fit good, metal

Update to original comment below. Customer service reached out to inform me that you can loosen the screw in the middle to allow maximum movement up or down. Just wish the box would’ve had instructions for that before throwing them away.DO. NOT. BUY. The rear sight does not move up or down enough to zero in. Even at the “max” up the groupings barely moved. Save the money and invest in a better quality sight.
