Great Sights for the Price

by Claytonian, Gear Expert from KS, United States Written on July 18, 2023
I think these sights are great for the price! And I love the grey color, great match for my grey themed build. I also have the FAB OPMOD skeleton buttstock, it's great too. Everything came together nicely. No issues.
Most Helpful Negative Review Adjustments Don't Function
Purchased these as a back-up set of sights for am AR-15 rifle build, since I've love FAB defense products in the past. When I took the rifle out to sight it in, the iron sights would not adjust accurately (windage or elevation). I finally got the sights to adjust up (after like 15 turns to get any response) but they jumped from no adjustment to 8" high. When I adjusted them back down, the grouping stayed in the same location. I finally gave up on my iron sights and sighted in the Red Dot with no issues. Just save up the money and get a good pair of metal BUIS.

Avoid these sights by all means.

by Rosco P. Coltrane, Verified Owner from NJ, United States Written on January 8, 2025
These sights are not good quality. Why?

They are some sort of plastic/polymer.
They are not quick to manually flip up
You can loose your zero easy, due to easy and quick to rotate dials

They are better than nothing, but the cost of which to zero the sights make it not worth the purchase.

Unfortunately, I threw away my money and resorted to purchasing a new set of far better quality sights.
Pros:
  • None
Cons:
  • cheeply made
  • loose zero
  • not easy to flip up
Would recommend: No

Fills the roll perfectly

by MOSO, Verified Owner from NC, United States Written on October 9, 2024
Got this set on sale for right at $40.00. They are mounted on a Kel-tec sub 2000 used as a “truck gun”. They are solid, but are manually deployed. They are perfect for their intended purpose. They are 5 star if being judged in a category of other manual polymer sights….. 3 stars when in a category of say Troy or other similar sights.
Pros:
  • Affordable and durable
Cons:
  • Manual operation
Best Used for:
  • Affordable builds
Would recommend: Yes

Cheaply made

by eyko87, Verified Owner from CA, United States Written on September 13, 2024
These sights are made poorly, the Allen wrench that comes with them and the set screw for the sights will round out after barely any tightening. They are wobbly and bulky. Would not recommend.
Would recommend: No

Not great but they sure are light!

by Anthony, from CA, United States Written on September 1, 2024
The sight picture is just ok. I wouldn't want to actually use these in an emergency, but they are the lightest flip-ups I've ever used. So if you want a lightweight set of sights that you don't expect to use, they may be a good choice. In any case they'd be a lot better than nothing!
Pros:
  • Lightweight
Cons:
  • sight picture
Best Used for:
  • emergency
Would recommend: Yes

save your money!

by KC-Gun-Guy, Verified Owner from KS, United States Written on August 13, 2024
These sights are NOT good. Save your money. Mounting screw stripped when trying to install. Purchased on sale and they were a waste of $40.
Pros:
  • No pros - dont waste your money on these!
Cons:
  • the mounting screws strip easily!
Best Used for:
  • Filling up the waste bin!
Would recommend: No

well designed and sturdy

by B, Verified Owner from PA, United States Written on August 13, 2024
Just got these iron sights for a rifle I bought that came “optics ready”. They attached securely to the picatiny rail no issues. I really like the adjustments on them to zero - crispy click. They seem very robust but have only owned them for a short time so cannot comment on longevity. The framing of the front sight is also really good it helps you center the rear one better.
