I got My First AR This week. a used Bushmaster XM15- E2S. Collapsible butt stock, rear sight/ handle on a picatinny   rail. stock front sight. being a Army Vet I know the basic. i want to deck it out. I need advice. 1) I want new Forward Hand guards w/ rails,2) a scope mount & a leupold scope i can use for hunting.  3) I want "iron sights" i can use without messing with my scope. That's what i want for start. is there any brand i should stick too or avoid?

Thanks Y'all
Ken

Centurion Arms for the rails, Larue LT104 with scope of your choice and Dueck Defense 45 degree sights.

You didn't specify a budget so this might get a little expensive
