All right, so it looks like I'm getting a 16" PredatAR 5.56 as soon as we sit down and order the thing.
So, I'm guessing that he's just going to buy the rifle - if that's the case, then it will need sights. I think I want to put an RDS on there, maybe with magnification, but right now I'm not ready to throw down for an Aim Point which is what I understand is the way to go.
I'll probably just put irons on for now, I'll at least want BUIS no matter which way I go with optics. Are the troy industires fold-down BUIS the best way to go? Any other good options out there? Any pearls of wisdom as far as sights/scopes/optics that you guys can share?
Thanks to everybody that replied, I think the PredatAR is going to be a much better fit than the OBR.
