I know about the whole actual brand/name/manufacturer thing. I'm just wondering what they were like. Quality of their stuff regardless of price.
Cyberguns, and Umarex rebrand guns. Umarex is higher end in comparisson to umarex, rebranding brands like VFC (416), G&G (Mp5s), etc but, it's unlikely you'll find any of these in stores as they only carry the stuffty guns. Cyberguns rebrands clones and chinese brands, Cyma, Dboys, etc. They might slap on a few trademarks and give it a "licensed nametag" but, no matter which way you cut it, you're still eating the same cake. They mark up the price because people who buy from sports stores are stupid.
In the end you're better off buying online. At airsoftGI any purchase of $100+ gets you free shipping and you can couple it with a %10 off coupon. (HOT or Tim.)
