While I'm still waiting impatiently for my RRA to arrive, I've been thinking about buying another uppper, perhaps something more suited for downrage shooting that I could switch out or eventually just end up using it in a 2nd rifle.
My question, when Iook at uppers, some of them cost more than a complete rifle.  What makes a $1300 LaRue $1300 vs say $500 from somewhere else? I"m not at all opposed to paying for quality, but I want to get a better handle one what I'm getting.
Also, this is a total newb question about building a rifle.  I get a bit comfused when I read posts about uppers, complete uppers, and lowers.  it seems those terms mean different things to different people.  I would like to buy just the major components to put the rifle together.  My thought is that would be a complete upper (like the LaRue or LMT), a complete lower, then obviously a stock and grip.  Am I missing anything?

Anyone? Anyone?



... or did I ask just that stupid of a question that I should be ashamed of myself?

Got it.  What makes some complete uppers up to twice as much like the LaRue?  Is it primarily the barrel being of signifcantly better quality than what you'd get say from a Bushmaster or RRA?
