## Customer Reviews

### ⭐⭐⭐⭐⭐ Solid build, easy install
*by D***. on April 1, 2025*

These do exactly what I needed them to provide: a back up set of sights to my Eotech!

### ⭐⭐⭐⭐⭐ Low cost and well made iron sights
*by @***R on February 28, 2025*

Just bought a S&W FPC which doesn't have sights. I was looking to add a set of low cost to it, knowing, you get what you pay for. THESE sights, while low cost, are EXCELLENT! Well made, adjustable without tools, and have a nice release button when you want to fold them down. Definitely look at these if you're interested in getting iron sights.

### ⭐⭐⭐⭐⭐ All around decent.
*by M***. on April 8, 2025*

Very easy to install. Very easy to sight in. Are 100% co-witness with my Sig Sauer Romeo5 red dot on the riser. An excellent backup to the red dot, especially for the cost.
