They new thing is 'Cansoft'. The frame on those guns are clear, but tinted so its hard to tell. KJW has some decent guns, I've had a few but alas they don't match up to superior quality like Tokyo Marui.
If your 18+ look into getting age verified on this site, doing so will grant you access to the classifieds where all the wonderful, black, full metal guns await you.
If you are underage, unfortunately the only advice I can offer is for you to wait till you are of age.
