Guys.. i have a question. Those of you who own the Troy iron sights (Non micro set). How are they cowitnessing with Eotech? I have Magpul Mbus front+rear and cowitnessed it with my Xps2-0 on my first AR without the need of any riser. Are the Troy sights height front+rear heights the same as the Magpul's? I'm still thinking which sights should i get to cowitness with (another Eotech Xps2-0 or 552) on the SBR i'm building. Thank you for any inputs.
