How does one decide "how much better" they need? How do you determine when "good enough" really is? How do you decide which features are useless and which are needed? How does one put a price on quality? Why would one opt for a product of lesser value for a similar price, or of similar price but lesser value?
IMHO, I would greatly prefer to have a $500 AK than a $700 AR. Yes, many of those sub-par ARs can be improved with a few whacks of a punch in the right place, but little can be done about sub-par barrel and bolt materials, or low quality internal parts (something that doesn't even appear on The Chart) without spending money.
Personally, I see no point in settling for "as good as". Far too often people wind up spending more on a sub-par rifle and CAA or Crapco bolt-on garbage than they would spend on a quality rifle and a decent optic. Frankly, I'd rather have a 6920 and run iron sights than a RRA or Bushmaster and run an optic.
If I was in the AR market, and thought I was limited to a budget of $700-$800 I would bring my lunch, cut back on the beer, and maybe get a side job and save up the extra $200 to get an M&P or a CD LE model.
He needs to decide what he wants to do with it (I'm assuming plinking at the range and possibly HD), figure out a budget on how much he wants to spend, and then research from there.
I agree COMPLETELY. Although, once properly educated, I don't see how anyone would want to settle for RRA/DPMS/Oly, etc.
