...ok, I bought a scope first, then the rifle. It's my first AR platform.
The scope is a US Optics SN3 TPAL 3.2x17 w/ EREK; low profile housing.
The AR upper is an Armalite.
Do I want/need a 20moa base w/ the EREK?
Please help me choose a good quality base and 30mm rings.

Sure would appreciate it if you would share your experience and knowledge with me on this. Thanks!
