Night Vision Scar 20 PVS-22

Have any of you used a clip-on device with your Scar 20? I have a PVS-22 that I would like to us with my 20, but I have been hesitant due to the know optics issues on the 17. Does this apply to the 20? I'd hate to destroy my PVS-22, but the 20 is otherwise perfect for it.
