I have the Eotech XPS2-0 and co-witnessing with Magpul mbus gen2 front & rear sights. Now im kinda interested of getting the Eotech G23X magnifier. The question is.. if i put the G23X infront of the Magpul mbus, will it touch? Or i need a 7mm riser for the G23X? Thank you for any inputs.. appreciate it.
