Are their any airsoft guns equivalent to the unbreakable tippmann in paintball?

Best quality is Systemas but they are 1000-1500 dollars. I would go for the G&Gs which have amazing quality. Their full metal guns (most of them) are made of magnesium instead of regular aluminum making them very durable and lightweight. G&Gs also have 25000 rpm high torque motors along with incredibly strong internals. Look at G&G on evike.com. Also, for about 100 dollars more, you can buy a KWA. They have fps averages around 420 fps and also have great quality. Personally, I use G&Gs and love them. G&Gs average about 300 bucks and KWAs around 400 bucks. Just look them up on evike.com. Oh and don't forget to look up G&P.
