Hopper and Air tank, also a Custom Products two piece barrel
Fast, quiet, sexy, accurate
None when I tested it
I first used it and i loved it, I am saving up for one currently and i perfer this over a 98 custom. It looks nice and shoots smooth and fast, the Taodao Board ( not sure how to spell it) is very sleek and easy to use. the gun right out of the box i okay accurate but if you upgrade the barrel the it shoots like a charm.
