Great product at a good price - Magpul Industries MBUS 3 Front Rifle Sight

The iron sights are very sturdy and appear very durable. The flip-up buttons work as intended. I love the FDE color as it matches the rest of my build. Only reason I gave 4 stars is that they are a little challenging to connect to the picatinny rail but that does mean you never have to worry about them coming loose or falling off.
