I actually just got a set of these new Rainier Arms BUIS in for review and am very impressed with their initial look and feel. You can always feel the difference of a good quality product when it is in hand and these have that feel. Literally have only had time to open them up and fondle them a bit but will get them installed and in use asap. Here is some information on them if you are looking for a nice new set of BUIS.

We designed the Rainier Arms backup-sight so the small and large ghost ring is on the same plane. It is not necessary to change the point of aim when the distance at the target remains unaltered. No tool is necessary to alter the height of the front sight. The Rainier Arms backup-sight is suitable for all AR 15 front sights having a 8-36 UNF thread. Because of this a large variety of after market front sights may be used.
The combination of steel parts where absolutely essential and high grade aluminum parts wherever sufficient, gave us the possibility to implement a sight with minimalistic design, low weight and minimum height.
Thanks to a special surface treatment all parts are corrosion resistant to withstand even maritime conditions. The spring- loaded folding mechanism reliantly protects the sight from damage when used under rough condition in the field.
The Rainier Arms backup-sight with its very low design in a height of only 9 mm / 0.35” allows to be used with extremely low mounted optics.
