So far horrible service
I ordered part on 1may, it was supposedly shipped on may 3rd. I havent been able to track because it says it hasnt left yet. I have called, no answer, i have written emails, facebook messages and chat messages and had no feedback. I have a feeling i would like the part if i received it. Gary 904-616-9021

Good back up sights!
IF you loose your primary targeting system you must have a back up. The cheap way to go is the polymer flip up. I have used them for years and practice switching systems. I have noticed that the metal pop-up back up sights tend to hold zero much better. Again, they don't have to be the most expensive out there, just good solid sights that fit your rails. You should zero your sights if you have removed them. Polymer = Good, and Metal = Better. RH

Excellent sights
These sights are as good as Magpuls, but what a deal! Had no problem installing them like some others who had to force them. Just take out the screw, then slide it on from the end of the rail, then put the screw in when it gets to the point on the rail that you want it. Easy as pie! I like that the front sight post doesn't need a tool for adjustment. I wish I had ordered two of them for both of my ARs at $26 each set. You won't be disappointed.

Seem to fit well on my AR's!
Nice Products! Remember polymer is polymer and CBUS Polymer does not directly replace machined metal sights; however, I am please with the quality for the cost! Alternative to Magpul MBUS. I have not fully assessed or mounted yet; however, hands on inspection appears the quality in the product is there!

Cbus polymer sight
Good sight the only thing is if you use the small appiture you have to fold it deck to large for it to lay down flat.Good product for the price.

good buy and good quality product
The sights are of good quality and the spring action plus sight adjustments have a positive feel. Definitely worth the price. I would have gave 5 stars, but the screws are cheap and the threads stripped easily. Went to the hardware store and got replacements for $1.00. I also got no response from their support regarding the stripped screws.

CBUS polymer buck up/flip up sights
The product does seem nice, fits and flips well. However the nut / bolt on the front sight stripped on initial installation. I replied to them about this in an e mail but got no response back from them. So...Buyer Beware. Wess

Worth the money
Noticed a small Crack in the polymer where the nut is. But its still holding

Great value
These work well and are solidly built. I will likely buy again for my (inevitable) next build.
