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.

Look Good, But Don't Fit Snug Enough

by Cory Schoonover, from OK, United States Written on September 24, 2026

Way too loose on the standard rail I have. There was nothing that I saw in the description for me, that said it would not fit a standard picatinny rail. But it doesn't fit the rail of my CMMG Resolute Complete Upper.

Pros:

Aesthetics
Fair Pricing

Cons:

Much too loose of a fit to be useful

Best Used for:

Nothing that I own

Great sights at an unbeatable price. Already had a set purchases a while ago at almost the full price. These were well below the original price. Easily installed, and easy to adjust for zeroing.

Decent set of sights

by J, Verified Owner from CO, United States Written on August 6, 2026

The sights are lightweight, low profile and easy to deploy. One of the advantages to these sights as compared to Magpul is the ability to install them without having to slide them onto the rail.

Ehhhhh, Just do magpul

by Todd, Verified Owner from SC, United States Written on July 28, 2026

Bought these on a cheap deal and they are alright. No spring assist and they are kind of hard to get up - they just feel very cheap which to be fair they were. I would just spend the little extra to buy the magpul ones next time. They look good, just don't function all that well.

FAB Defense Front Sight

by Joey Z., Verified Owner from TN, United States Written on June 18, 2026

This product is garbage because it came with a stripped out bolt, and it can’t be replaced.

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
