If all else fails, check over at ar15.com. Got whole sections devoted to AR's, AK's, and FN-FAL's. And no shortage of people willing to offer their opinion on anything.
Yeah... prices have really gone up on those. I'll probably just get the Aimpoint.
Does anyone know a reputable FAL dealer? I'm looking for one in metric - the US-made models are way too expensive. (Might as well buy a M1A).
