This is a very solid build. Everything about it is tight including putting it on the rail but that is fine. I Co witnessed it with my new Aimpoint Pro. It is very nice. I have several Magpul products on my AR and they all are high quality and serve the purpose perfectly as designed.

Very well built yet lightweight backup sights. No play whatsoever in their operation, whether folded down or upright and in use. The multiple apertures on the rear sight stow flat, thus maintaining a low profile and minimizing interference with other optics on the top rail

Quick n easy FDE backup sights should be a no brainer. Easy to install, looks great, easy to flip up when needed and out of the way when not. These look great on a black broomstick, and fit snugly. I have them in black, FDE, and a few other colors, and they all look great.

These sights are light weight and great as back up sights. The gray color looks awesome! They tuck away under the optics. Very accurate. Easy to install and remove. I highly recommend these sights in gray color!
