I'm interested in the Crown but I don't see any .30 in stock anywhere. Want one of the laminate stocks, probably pepper or yellow. I see that Krale has all the parts -- base, barrels, stock. Any reason not to just build the gun I want? Price of the three components looks essentially the same as buying it pre-assembled. And if this is just a lego project (putting aside tuning, which I'd need to do regardless), suggestions re: barrel length? This would be a pure target shooting platform. I feel like this is too easy so must be missing something. Thanks in advance.
