There IS a best company that makes the best gun, it's a systema PTW and it's about $1800 lol
G&P would be second coming in at 650-800 new
You didn't buy a horrible gun, you just need to get rid of some of those horrible stock parts. Typically all AEG's, no matter how much you spend, perform only adequately brand new. There's ALWAYS something that needs to be upgraded internally.
Once you become a veteran, you'll realize that the only thing that matters on a new airsoft gun is the quality of the body, because you're going to be replacing all the internals anyway!
