Nothing except for the hopper adaptor clip & remote or/and bottom line.
Strengths:
Accurate - Very! even with dimpled paint!!
Distance - holy crap, this gun shoots far!
Noise - 1 loud MF...I love loud guns... Mine received the name "The Cannon"
Ballbreaks - rarely (3000 rounds, 1 ball break - easy fix, lightly coat the inside of the magazine with rifle oil inside)
Weight - very light
Feedrate - Fast, I unloaded a magazine in alike 2 seconds - even semi is fast!
If you bend a few pins, just bend them back into place with your thumb!
Maintenance isn't that hard - Just keep that manual near you... You don't really touch much on there.
Very consistent
And people won't stop asking questions about it!
Weaknesses:
Expensive, easy to break, front loader kinda sucks (port needs to be open more-I think the newer version has that done already, not sure)
Most fields won't let you play in full auto (luckly there is a screw hole to turn off full auto) But you don't really need it! :)
Conclusion:
I wouldn't reccomend this gun for the beginner. But if you take apart guns all the time and you want something fun, get this one!
