I got an A-5, pretty stock I will sell you. It DOES have Response Trigger. Also comes with 4co2 tanks (2 large cant remember exact size, 1 14oz, 1 9oz) a NIB Tippman Vectra mask, barrel condom, pair of gloves, and if you would want to spend the extra money on shipping I'd throw in 1500 paint balls for free (what the **** would I need them for? lol).
Send me a PM if youre interested
