Exceeded expectations - V Seven AR-15 Enlightened Upper Receiver, 2055 Lithium/Aluminum

Machining quality, fitment, and precision of the threads were all impeccable, and it is indeed light weight. Charging handle (Radian Raptor) and milspec BCG glided smoothly in their respective channels. Face was true, so didn't need any truing; I've assemble nearly three hundred uppers in the past couple years, and every single one, with the exception of VLTOR's MURs, needed truing to some degree, so this was a pleasant surprise. The material itself is claimed to be some wonder alloy, but I can't speak to the veracity of the manufacturer's claims. What I can tell you is that the coating doesn't play well with the alloy, or the upper was not cleaned properly prior to anodizing, and it wears much faster than it should. With that being said, as awesome as this unit is in theory, I don't think the price is justified, unless you just REALLY want to flex on your friends. In which case, flex away.
