Most Helpful Positive Review Killer sights
Really good and easy to use sights. The best part is no tools needed too adjust. Installed in less than 2 minutes and I was ready to go. For the money you can't beat them. When they're down I can still see through my sightmark red dot as well. If you're in the market for pop ups sights you can't go wrong with these bad boys.

Sight is fine

by Steve House, Verified Owner from UT, United States Written on April 29, 2025
But the hex bolt threaded after just one use. Lucky I am okay with the front sight with other mods.

Good quality sight

by Chief O, Verified Owner from OH, United States Written on April 13, 2025
The Fab Defense TMDFS is top quality. Detent is hard, sits at the perfect height for co-witnessing with an optic. Locks firmly in" up" and won't move when shooting. Very satisfied. And don't forget the Fab Defense rear deployable sight for the perfect aiming tunnel.
Pros:
  • Does the job completely
Cons:
  • none so far
Best Used for:
  • Target acquisition

FAB Defense Top Mounted Deployable Front Sight

by Ziimo, Verified Owner from MI, United States Written on March 7, 2025
Was looking for a pair of backup sights for my build. At first I was leaning towards getting the Magpul MBUS Gen3's but came across these Fab Defense one. After watching a few video reviews and reading up on these I was sold on them. They are manual flip up/down not spring loaded like the Magpuls but that's ok for me. Also they are about half the cost of anything else out there.
Pros:
  • well build
Cons:
  • None
Would recommend: Yes

Good quality for polymer sight

by E, Verified Owner from OK, United States Written on May 19, 2024
Quality seems to be on par with magpul. Sights are manual flip up and down and do not lock into place. Haven’t had any issues with them staying locked in place so I don’t see this as an issue at this point in time. Would buy again for bargain polymer sights.
Pros:
  • Low profile
  • Light weight and easy mount
Cons:
  • no lock in place when folded
Would recommend: Yes

Best Polymer Sights for the Money

by Eugene Moses Kalashnikov, Verified Owner from OH, United States Written on January 10, 2023
These come in at a great value in my opinion. I was a little hesitant at first because there is no manual locking mechanism for the sight in the upward/downward position, meaning I'd like to have to push a button to fold them up/down, but my worries were eliminated once I felt how solid the lockup was. These detent nice and firm in the up and down positions. These sights are also easy to adjust. As a bonus, the aesthetics happened to match my Sig Romeo5 red dot perfectly and they co-witness like they were meant to be used together. I ordered this separately from the rear sight which was cheaper than buying them as a set.
Pros:
  • Lightweight
  • durable
  • Affordable
  • aesthetically pleasing
  • easy adjust
Cons:
  • None
Best Used for:
  • AR

Great backup sight

by Will, from AZ, United States Written on April 20, 2022
I have an AR-15 and the front sight had a cheap pin that broke when I was trying to adjust it, so I ordered this one and it works great! I love the dial adjustment. I have it dialed in for 25 yards right now and it is super accurate.
