T1 AR5 Cowitness BUIS

[DwayneZ]

I am looking for a not so expensive T1 QD cowitness mount around 2.5oz or less.

I saw some reviews of the Scalarworks item, reviews not so good for the QD part.
ZroDelta is an option, but both are rather costly.

Suggestions?

Scalarworks hold zero. The T1 mount is excellent and requires no tools. I have to ask, what is not so good about the QD part? I admit it isn't as fast as throw levers, but it also isn't as obtrusive.
