Tough Tactical Tools Back Up Iron Sights, Flip Up 45 Degree Offset Back Up Iron Sights, Universal Picatinny Rail Mounted BUIS

Work great once installed but they don't flip up and down with the push of a button like the Magpul MBUS sights so you'll have to unwind the wheel on the side and teist it back in to lock the sights up or down, which can be a pain. So for that reason alone it's 4/5 for me.Pro: They are full metal and good quality.

Work good after you flip them up a few times was kinda a pain to get them to work one is a little lose but not to bad pretty good for the money

A helluva good solid product, I lovem

I like them, for the cost and easy to use. I don't know why people are commenting on unscrewing the screw to get them to flip up, when I just push the "button" and they flip up or fold down.

Very fast delivery. Very nicely built, all metal, one button flip up operation, adjustable sights and they fit great on my AR! Very impressed with quality

Free Will made Easy to install little hard to get into pop up but after you work with him awhile they do great

Mounted perfectly on my rifle. Hope I never need them but glad they are there just in case.

Not a good item whenI installed it on my shot gun and the threads strip out easy. Be careful
