The Kraken, is a mixed batch of lemons. You'll either get one that will work, or you won't. Most people will suggest a Kraken be used a project gun, but I'm sure it's fine as a starter. I used to use a Kraken as a starter as well - never had any problems, and when the money built up, I simply got an Armalite from G&G.
