Hi, Moodster back and I guess I can’t stop trying to solve issues. I think I really appreciate JoeFriday’s suggestions as they parallel my think and search for the right optics.
After literally weeks of studying optical options and contacting optics manufactures for a magnifying sight (beside just a 1 X ‘Red Dot”) for the S2K I think I have located what I was looking for. I ordered a TruGlow Red-Dot 2 x 42 mm sight that fits onto the MCARBO flip mount. It is 5.3 inches long, has unlimited eye relief (very important on this gun), and weights in at about 8 ounces. It is a medium quality magnifying sight but better than no options.
This frustrating search (I purchased 3 different systems in the process) did give me a product idea which I sent to MCARBO (I am sure that others with the same thoughts would help push for it). I found that I could have used the Tacticon Red Dot plus their 3 x flip to side magnifier EXCEPT that the flip base for the magnifier (about 1/4- 3/8 inch thick) which had to bolt onto the top rail prevented the gun from folding and latching by about ¼ to ½ inch. I would imagine that anything bolted to the top rail would have to have a lever release mount and then be removed before the gun could fold which kind of nullifies one of the guns big features. I also found that the lever release mount added height and made matching to the Red Dot a real fight.
Possible solution: If MCARBO made a rear buffer plug that raised the latching mechanism by about ½ “ you could leave any accessory bolted to the front rail (as long as it either flipped or was on a 45 degree offset mount).
I hope this helps someone else from going through all of this!
