## Customer Reviews

### ⭐⭐⭐⭐⭐ Sturdy and easy to sight and mount
*by A***I on August 6, 2025*

Love these thing tactile, great visibility easy to sight, mount very secure, the fiber optic great in sunlight

### ⭐⭐⭐⭐⭐ Great sights
*by P***R on June 17, 2025*

Works Great on AR-15 chambered in 350 legend

### ⭐⭐⭐⭐⭐ Tactical and versitile
*by R***R on November 21, 2024*

These are a great bang for the price. They are made out of metal, the push button flip-down response is quick, and they stay true to the aim after recoil. One thing to note is by using them flipped down you can also use the rear sight post as it has a built in rear aperture for that function. However, the sight hole is very small compared to it's normal one that's used when it's in the upright position. The rear sight's ability to pick up light is great, even in dim lighting. it glows green in bright light and yellow in dim lighting making it easy to align with the red glow tip on the front sight post.
