I bought a new one yesterday and was thinking of the best and least expensive way to mount an optic so as to still be able to use the factory sights. I think I'd prefer the dot above the iron sights and shift my head down if I wanted to use them instead.

On my two Bushmaster AR's, I use a picatinny rail on the handle and an Aimpoint on that. I wondered about adding a handle to the 15-22 but then read about you guys talking about raised mounts and cantilevered mounts and started getting confused.

I'd likely use a TRS-25 that I also use on a Buckmark pistol or maybe just buy a second one.

Photos/links to what I might consider would really be appreciated!

The 15-22 is no different that your AR's so why not set it up similarly? You could go with a red dot sight or scope based on your preference. Check out the picture thread. There are lots of examples there and you could mail the poster about their optics. The TRS is a common red dot used on the 15-22 and should cowitness fine.
 
The sight on a rail on a handle on a rail is less than optimal. Get a .8" spacer or something like a La Rue or DD Micro mount and put the red dot on there.

A sight on an AR-15 style weapon should be 2.5" from the bore. This is how the stock and sights were designed to be used. Anything more is incorrect and means you won't be holding a proper cheek weld.

I am too looking for that (TRS 25) but in the mean time (the backorder...) anyone has the Vortex Co Witness sights & dot Combo installed in the 15-22?

I believe they are UTG, a compact ITA red/green dot and flip up sights with a .5" high 3 slot riser mount for $100 and some...

Anyone?

TRS 25 and utg high riser. Works perfectly

Set it up just like any AR. Lower 1/3 co-witness. I use an EoTECH XPS2 on a LaRue LT110 QD for my 15-22. This setup give me a perfect lower 1/3 with the Magpul MBUS sights that came on my MOE.
 
I picked up a Primary Arms red dot on a canti-lever mount.... set up to be as close to my "full size" AR as possible. (For less than $80 delivered it does a great job!).



Since this photo was taken, I added some PTS Magpul flip up sights.... but even with these, the co-witness was not a problem.
