    Great value, good BUIS.
  

*by D***I on Reviewed in the United States on December 25, 2017*

I could have ordered back up sights when I ordered my rifle, for an extra $249. But I really couldn't see spending that much money on sights I don't plan on ever using. These attached easily and fit well. When sighting in, I had trouble with the adjustment tool for the front sight. It didn't seem to fit properly. As a result, I wan't able to get the elevation right. The windage adjustment on the rear sight worked fine. Back from the range, I was able to get the front sight adjusted, with the help of some handtools. The post was binding a bit and a drop of oil helped free it up (to be fair, the instructions state this). About this time, Mike from Dagger Defense wrote to ask me how I like the items I ordered. I explained the issue with the front sight tool and Mike said he'd a replacement set out ASAP. I told him he didn't have to do that, the only real problem was that the prongs on the tool were a little too big to fit the notches on the sight. I had, in fact already fixed this by filing down the prongs a bit. But Mike sent a whole additional sight set, with another tool. The post on this set was moving freely but, alas, the adjustment tool had prongs a bit too wide as well (approx. .072" compared to notches .062") again, a touch of the file and all is well. Excellent customer service!

    Exceptional Customer Service
  

*by M***G on Reviewed in the United States on February 15, 2019*

I used these DD BUIS for the first time today and I really like them.  The front sight broke, however, and it wouldn't lock in the down position like it's supposed to.  I e-mailed Dagger Defense and Mike immediately sent me a replacement.  Wow!  I'm impressed!  The front sight did fail but Mike made it right!  As I told Mike, this was the main reason I chose DD BUIS.  I read about similar positive experiences with their customer service so I decide to go with them.  It's refreshing to see a vendor stand behind their products.  Mike did!  Thanks.  Martin

    Excellent quality at an affordable price
  

*by A***E on Reviewed in the United States on October 8, 2017*

I am impressed. The quality of these sights is on par, with sights that have cost twice as much, or more.I recently built the least expensive AR pistol that I could put together. I wanted to stick with the theme, and by some very low cost flip up sights.I chose dagger defense, because they are NOT polymer, and they are very affordable.Honestly, I was not expecting much, but these turned out way nicer than I thought they would be.I will not hesitate to buy dagger defense products in the future.
