Most Helpful Negative Review Guess they are ok.
Got a pair of these and I guess they are ok. They are NOT spring loaded like Magpul sights and the look gives your the impression of CHEAP made sights. I may end up taking these off and putting them on a throw around rifle. They look little cars when not flipped up. Guess I would recommend if your t...

No bad for the price.

by Steve, Verified Owner from LA, United States Written on August 12, 2025
The sights are bad for BUS. The only thing that I don't like is that they aren't spring loaded like the Magpul BUS.

Manually Operated back up sights

by Jimmie Hawkins, Verified Owner from TX, United States Written on August 5, 2025
I’ve been shopping around for back up iron sights for a while. I came across these on my favorite site OPTICSPLANET!!! And the deal was indeed “Blazin” - These slapped right on my 10.5 inch AR and were a breeze to zero through my existing optic. I actually like that there are no springs or buttons to malfunction - Highly recommend these little guys from FAB
Pros:
  • Eas of use.
  • look & design
  • Ease of install
Cons:
  • Were spendy without the blazing deal
Best Used for:
  • Backup or Static Iron Sights
Would recommend: Yes

These sights are easy enough to use

by George Williamson, Verified Owner from NJ, United States Written on July 24, 2025
These sights were an easy install and adjust without tools. They appear durable enough for most situations. Acquisition of sights is also easy enough.

Not sure how tough they are but…

by App 1969, Verified Owner from GA, United States Written on May 28, 2025
Not sure how tough they are but… Accurate and I like the fact they don’t pop up. They are silent as you push them into position. In a combat situation it may or may not matter. But if you’re trying to be stealthy a loud pop as you engage other brands could give your location away. These slide up with little effort and are almost silent.
Would recommend: Yes

Defective Product

by Mark, Verified Owner from TX, United States Written on September 13, 2024
I put on the front sight no problem. Then I went to put on the rear sight, but in doing so, the hex key stripped the screw. Like, completely stripped. This isn’t my first rodeo so I’m guessing the screw was of low quality. Now, with the rear screw stripped, I am unable to take the rear sight off. Optics Planet claimed no responsibility. They said to take it up with FAB Defense. Typical retailer -> manufacturer runaround.
Would recommend: No

bad batch?

by Steve, Verified Owner from AL, United States Written on July 10, 2024
This would have been my 4th pair of fab sights but I had to return them because the hex nut on the rear sight came stripped. Normally they are a great product.
