Great product.
This set of back up sights are just what I needed. No problems yet.

Awesome Quality - As Good or Better Than Magpul
Mounted to my new 5.56 carbine build. These sights operate flawlessly. Recommend for a flat top upper. Great product and will definitely buy again for future builds.

Pleasantly Surprised
I'll admit, I was a bit skeptical ordering these sights as a replacement to the MagPul BUIS I have used for years. I, however, noticed right out of the box that these were made very well and would sustain years of rough treatment. For less then the price of one Magpul sight, you can get both front and rear of these sights...really a no brainer!

CBUS Polymer Sights
These are nice back sights for the money . I had two minor issues with them that I have resolved . The longer range sight . the smaller hole gave me some minor vision issues . I found it was smaller than my Magpul sight aperture but a 1/16 drill soon resolved that issue . Second was the dimple on the same sight . When the sun was at my back I found that there was a reflection that obscured the sight . This may have been from my glasses but it also was resolved with a little flat black paint . These minor inconveniences were why they didn't get 5 stars . I use these on my Tavor . They are quicker into action when needed than the factory sights .

Quality product for the price. Have viewed similar products from other companies and the difference isn't worth the price increase. Quite pleased

cbus polymer -- good sights

Not bad
not a bad sight for the money, my only issue is that the sights don't lock in the up position, they use only spring pressure to keep them up but its not a deal breaker for me.

Great sights
These are the best bang for your buck. I was a little skeptical about these because of the low price but they did not disappoint! Great alternative to all those overpriced sights.
