Polymer Flip Up / Back-Up Sights

The sights went on quick and were right on

These will work as a backup, but they don't fasten down tight and do not fit the rail perfect, so they tend to move a little on the rail. I also stripped out the screw on the front sight tryingto tighten it down so it wouldn't move. had to use a hardware screw and nut (which looks kind of stupid) to mount it. I likely wouldn't buy these again unless I was desperate to finish up an AR with a scope.

Worked really good at the gun range at 20 yards. Per the Range Master just make sure you lower the front one level neutral and start from there. (level with the shoulder of the body). For a low budget build the sights, charging handle, barrel and 15" rail worked great together and the price was the best part. Everyone at the range loved it.

Love the way these flip up and how easy they are to lock down, however, when mounting them, they tend to rock to the front and back even after tightening down. I tried to tighten them more to see ifthat would help and actually stripped the screw (it's just aluminum). Ended up having to use some real bolts to mount it. After using those, it did tighten it enough that it will work as backup sights but there are other sights for around $20-$30 I'll try out and compare. These definitely are NOT in comparison with the Magpul polymer sights.
