nice setup waffle, I personally like how the m3 looks over the 552 on that gun though 
Gratz on the WA GBBR... prepare to buy new trigger parts though...Thanks, and same, I really prefer aimpoints to EOtechs. Aimpoints have a long tube, so they work much better during the day. The reticle on EOtechs is unnecessary and cluttered. I just ordered a Tan magpul MOE GBBR kit by G&P
G&P WOK MOE Carbine Kit (Dark Earth)
and I think I'm going to put either an ACM UBR or PRS stock on it, and DD OMEGA rails and troy sights.
