I'm nto sure how helpful my reply will be, but I"m waiting on my Stag upper to come. I wanted some kind of basic optics...nothing super long range as I went with a 16" barrel.
but Randall at ar15barrels.com who's customizing my upper (I lack tools, and the balls to do it right now)...and he suggested no A2 front sight, as it will be in the way of the scopes field of vision.
So I instead opted to ditch that, and in its place I've got a railed gas block.
I don't know if the Eotech would be blocked by a front sight though.
