Outstanding iron sights! - Troy Tritium HK Top Mounted Deployable Iron Sight

I've been using Troy backup iron sights for 2 years now and love them. Once you put them up they lock in place and will stay there until you hold in the button on the side and push them back down. The HK style shroud around the front sight post makes aligning the sights much easier, in my opinion. These sights are definitely worth the money.
Pros: Very durable, easy to use, and stable.
