DD BUIS

This is probably a stupid question, but how do I switch aperature's on this sight?
I read the manual and the websight, but could not find the answer.
Thank you, Terry.

For the CSAT sight, and it's showing an A2 sight instead of an A1 like the DD, but I think it should work.

If all I have to do is flip it like a carry handle sight, it's stiff as hell.
Anyway, I'll figure it out.
Thank you, Terry.

If you are talking about the DD sight that comes on a DD M4, it flips back and forth between the different sizes. For instance, if you have the larger ring up right now push it back towards the butt of the gun, the smaller (distance) ring will then flip up. If the small diameter sight is up right now, push the ring forwards to the muzzle and the larger ring pops up. A few drops of lube and some manipulation of with the knob may help loosen her up too......this also works on my wife occasionally

Yes, I installed a same plane Ashley aperture in mine.

Wait, you're asking how to change from big aperture to small aperture and vice versa? Disregard my other post then.

Yes, just grab the aperture and flip it. I'd much rather it be stiff than floppy.
