Great product
Great product for the price Solid build .

Very well made sights.
I wanted a good pair of polymer BUS, and that is what I got. Sturdy, mounted well, good spring strength, and half the price of Magpul. Good buy, and if I need some more sights one day, I will buy these again.

CBUS Polymer Back Up/Flip Up Iron Sight | Alternative to Magpul MBUS
These back up sights are an ABSOLUTE value and I wish I would of ordered more. They work just like or even better than Magpul's polymers and making adjustments are a breeze without the need of special tools. I'm definitely going to order these for all my builds.

Great Sights, but not my favorite
These sights are functional, quick to deploy, and work well. The only thing I do not like is the attachment method. IF these could be attached with a throw lever or even a coin I would be happier. I just don't like needing to use tools for my AR. Other than that though they are GREAT!

for the price, their good
These sights seem well made. There are a few things I prefer on the magpul's, but at half the cost they work fine
-
Decent for price
Back sight seems to be good. Front sight post seems to be a bad design. It wobbles a lot. If that was fixed it would be a great sight

Great Products at Great Prices
New website lay out is much better and more user friendly as well

Cobratac CBUS
Wouldn't fit DPMS rail without tapping with rubber malet. They are working well so far.

Cheap Sights
Definitely you get what you pay for. There was some excess polymer on the sights, especially bothersome in the "peep hole" of rear sight. Fit and finish not up to par with Magpul. They do seem sturdy for "plastic" sights, but have not actually sighted/used them yet.
