I am in the process of building my first flat top rifle. I need an "optics plan" to start working towards. I see a variety of setups flip up BUIS vs non flip up. High mount aimpoint vs eotech or OKO. What about a fixed non lighted 3-4x? I need to get the uper first obviously and then a BUIS. What I need to know is what kinds of BUIS will work with what sight options?
I am interested in the CavArms A1 style apature, but it doesn't flip down. Does that limit my future optics choices? I see fixed BUIS' on rifles with scopes, how do people use the optics with the rear sight in the way? What about the front sight? (I really want a normal front sight)
I need a good rear sight because this is being done on a budget, and it will be a while before I get the optic. I don't think I will ever have the oprotunity to play with all the possible configs to see what I would really like so I really need some informed opinions heer.
