    • You get what you pay for
These are okay but not great. I do not see them lasting a very long time but they are cheap and will get the job done.

    • Good backup sights
I ordered these out of curiosity because I kept seeing Feyachi brand items on Amazon for good prices. They fit well on a rail and hold securely. As a flip up sight, they are quick and easily raise up. The sights are quick to see through and adjust. I do like the green and red highlight on them but I’m not really sure that it helps with quicker target acquisition. Not sure how much other Feyachi equipment I’ll order in the future but I am impressed with these. ... show more

    • Impressive well made
These are really well made. The front and rear sights both have a pin that when you flip them up they lock up. The pin has to be pressed in to lay them back down. The red dot on the front site is quite visible. The rear site has a small peep hole and when you flip it down the green dots are highly visible with the larger peep. The clicks are positive both for windage and elevation. They came in a small case that holds them tightly in place with no rattle. All in all I am very impressed. These are better than the factory sights that came on my rifle. ... show more

I ordered these sights to put on a 450 Bushmaster upper. The material, design, and build quality of these sights are TOP NOTCH! The rear sight adjusts for windage and front sight adjusts for elevation. Buttons to deploy the sights are easy to work and are sturdy. The red fiberoptic on the front sight and green fiberoptic on the rear sights are a nice touch and help with sight acquisition. They will take a beating with the 450 Bushmaster so I like that they are secured to the rail with an allen wrench versus a thumb screw. Quality sights, well worth it! ... show more

    • Good, but not better than Magpul
I got these for my 2nd rifle to replace the OEM iron sights to get out of the way of my optic. On the plus side, they're sturdy, the adjustment knobs are stiff and hold zero well as far as I can tell, and work pretty well as iron sights. I don't shoot beyond 100y with iron sights with this gun as it isn't meant for that, so I can't say too much about accuracy - if any sight doesn't work out to 100y it shouldn't be on your gun. The downside - The biggest problem is deployment. My Magpul BUIS are spring loaded and can be deployed with one finger pressing down on the button. These are not spring loaded and require you to press the pin in and pinch the sights and pull them into position, tying up two hands for a bit and taking your attention away from your target. Since BUIS are usually designed to be deployed when your primary sight/optic fails, time is usually of the essence. Now to be fair, the description does say that they aren't spring loaded, but I hoped they'd be quicker to deploy. The fiber optic dots aren't as good as I hoped, but that is something my Magpuls don't have, so there's a plus there. Overall for the money these are pretty good, but I won't be replacing my Magpuls on my primary rifle with these due to the time it takes to pop them up. ... show more
