Most Helpful Positive Review My 5.7 x 28 panzer AR
Simple adjustments and quick mounting. Perfect optics for my small rifle. Quick acquisition of targets.
Most Helpful Negative Review tritium not visible on rear sight
The actual quality of the sights are fairly nice. Easy enough to mount and set, however..the tritium rear sight is not very visable so might end up having to replace it. The flip action is also pretty sturdy. Only time will tell how rugged they actually are.

Self-Illuminated???

by Walt, Verified Owner from NH, United States Written on April 25, 2024
Good mechanical design....but I don't see the rear sight 'Self-Illuminating' under ANY light level. Is there some trick to get the tritium to glow? The front sight DOES 'Self-Illuminate' under pretty much any light however.

FAB FRBS SIGHTS SELF ILLUMINATED

by Adam, from FL, United States Written on March 12, 2024
Great product as advertised. Can’t go wrong with FAB Defense. Free shipping took 19 days but other than that I’m very happy with my purchase and Optics Planet Blazin Deals. Got these for much less than anywhere else. Worth the wait.

great back ups

by Michael Esposito, Verified Owner from AZ, United States Written on February 5, 2024
Made strong. Definitely designed for rough abuse and built to last. Not spring assisted, so manual flip up only. These sights will definitely not flip up if accidentaly hit during use. Very easy to see during low light use.
