## Customer Reviews

### ⭐⭐⭐⭐⭐ Really good budget option
*by H***S on July 3, 2020*

I have two sets of these. My example of two are very well made, and they make great budget flip up sights. They lock up tight with no side to side wiggle. The front sight post is also steel with a tool-less elevation adjustment feature built in. You won't find that on any other budget flip polymer sight. If you're planning to use your flip sights or irons as a main source of use, I'd still suggest spending the extra money on some high quality and proven brands like Magpul, Midwest or Daniel Defense. But if you intend your flip sights as backup to a primary optic, you really can't go wrong with these. They've been rugged and reliable for me and I'll continue to use then and purchase more in the future.

### ⭐⭐⭐⭐ Great quality for the price. Front post elevation adjustment requires no tools.
*by T***Y on May 11, 2020*

I can't see paying so much more for MAGPUL sights when there are thriftier quality options like this. They are solid construction polymer sights. I have no plans to torture test them, but I expect they could take some decent abuse and remain true. The front post elevation is adjusted with a built in dial. It is very stiff so I can't foresee it loosing zero easily. We still need to do some shooting with them to see how they hold up, but I think they will do fine. I have bought a couple of products from this company and found them to be very dependable. And surprisingly good quality for the price. I will definitely buy another set or two for future builds.

### ⭐⭐⭐⭐⭐ Polymer base
*by E***N on August 17, 2020*

Easy to install and priced reasonably. Took less than 1 minute to attach sights to my rifle. Material is hard grade plastic polymer base so hopefully it will last.
