(stupid question alert) Read a few older threads. lots of new scopes out there. Looking for an NRL 22 scope for my 8 year old. Can't be over $670 MSRP to stay in base class. MRAD with Christmas tree reticle. I've got an Athlon Argos gen 2. It's not bad. Bushnell Match pro sub tension on tree seems to be .5 Mil. Is .2 better?
