AR 15 Mag ?

[longranger]

I am doing my first AR-15 build using a factory assembled lower(RRA),Cardinal Forging upper with RRA bolt,carrier and charging handle.
Do not have the barrel yet but looking at 18"-20" Wilson SS from RRA.
My question is what magazines can I use, are Colt magazines OK or should stick with RRA,DPMS,Bushmaster and the like?
Am I to understand any AR-15 magazine would do the trick?

Yep, anything will work. But as with everything, there are different quality magazines.
