Most Helpful Positive Review Trinity Force BUIS
Good set or sights for the price. I’m using it as a co witness for a red dot. The material used is light which a plus to keep my at pistol as light as possible. When folded down it has a lower profile than most sights I had before.
Most Helpful Negative Review A little disappointed...not as pictured, no auto flip
So first off these seem to be relatively well constructed and decent quality for back ups. Main issue is that the picture showed the sort of "HK style" front sight and these seem to have been replaced by a different model that have a totally different front sight style. I wanted a cheap set with thi...

BUIS Backup Sight Set, Black

by Makers, from MO, United States Written on September 14, 2020
I would love to give this a five star review, but it’s a set, I was given two front sight posts with no rear sight post which I ordered the set, front and back. I will give it 3 stars because the front sight is awesome, guess I will have to order a rear sight to complete my set.
Pros:
  • easy to install
  • Easy to use & Light Weight
Cons:
  • No rear sight in package
Best Used for:
  • AR
Would recommend: Yes

Poor Warrenty and cheaply built.

I had a set on an AR pistol as back ups. Never really used them. Noticed one day after less than a year on the gun that a pin walked out of the rear sight and lost it and the spring to flip it up. They say they have a lifetime warranty, but want you to pay shipping to them and $10 to return. The shipping cost is almost as much as the sights new. I will spend the $20 and put into a better quality sight instead of paying them to replace on warranty.
Pros:
  • Cheap
Cons:
  • None
Best Used for:
  • junk bin
Would recommend: No

Pleasantly surprised when I opened the package.

by Casey Osborn, Verified Owner from NE, United States Written on February 27, 2019
I am building a 556 pistol with a bunch of extra parts that I have laying around. Being a budget build I found these sights for pretty cheap. When they arrived they were packaged nice and installed easy. Only thing is that they do not automatically flip up. Not a big deal to me as this is just a budget build.
Pros:
  • cost
Cons:
  • none so far
Best Used for:
  • back up iron sights
Would recommend: Yes

Good iron sights that are cheap. It works. Until I get a real scope, but I will still keep them as iron sights. Take this with a grain of salt though as these are the first iron sights I have ever purchased so if there are some amazing ones out there I wouldn't know.
Pros:
  • Cheap
  • metal
  • They work
  • Allen wrench included
Cons:
  • Can't see in the dark
Best Used for:
  • Backup sights
Would recommend: Yes
