Here's the tentative plan so far for my SEBR.  Troy rear BUIS & Aimpoint Comp M3 (2moa).  The BUIS will be the first purchase to get the rifle functional as well as to get me back into iron sight form. Later I'll get the Aimpoint with the eventual addition of a Gen.2 or 3 NVD.  The Aimpoint would probably be mounted on a Larue Cantilever mount to allow for the NVD. Are there any negatives to this combination?

 The 2 MOA appeals to me because it seems it would be more precise at the range and for possible hog hunting at night and could also be used on other rifles for hunting at 75 yards or less.  

 My only other AR so far is a heavy barreled varmint model with a high powered "normal" scope so all of the co-witnessing, etc. is new to me.  TIA for advice and comments, Bruce
