I didn't say the E1 was better than the KS but, technically it is as E1 does decent shimming and gives the gun metal brushings. I also never said clones are bad, I just said they aren't as good as some other guns stock.
Also, I own clones, all my AEGs are clones, I'm not anti-clones but, you can't even deny that they don't preform amazingly right out of the box.
