I've thought about it, but I went against it. I'm saving my xps2-2 and g33 for a daniel defense in the near future. My 512 and another g33 is on my JR carbine. My other g33 is paired with an aimpoint on my cz858, I thought about putting my trs on it with the g33, but I gave it to my wife for her 10/22.
So my sks is without third party sights, I might keep it that way anyways, I don't have many iron sights rifles left...
