I'm in the market for a new gun, and I've got $300 maximum, but $250 would be ideal. I'm a huge fan of AR style guns (M4, SR25, M16, ect.) and I want a longer gun, preferably SR25 esque. I want a full metal body and an RIS. Electric only, MOSFET not necessary, accuracy and reliability are major factors. I want 400+ fps as well.
