phantom stock class, stock barrel, adco e-dot sight, and a T-stock
nothing really, maybe a red dot sight. but it's great stock.
EVERYTHING!!!! it's very compact, no hopper and it takes 12 grams. my whole gun fully loaded weighs no more than three pounds. you can run and not worry about dropping your hopper or breaking paint. but best of all it's incredibly accurate, i was able to hit a coffee can at 120 ft fairly consistently as soon as i took it out of the box. this gun also makes you a better player, since it only has 10 shots you learn to make every shot count. it's very cheap to buy and to use, you won't go through nearly as much paint as with a semi.
i don't like the rock and cock part. that's all i can think of.
this is an excellent marker for any type of player. i would highly recommend this gun to anyone.
