Things I liked:I like the smooth bolt pull, the bi-pod, the 2 piece assembly, spare magazine, and the speedloader. Things I would have changed:Theres nothing I've found that I want to change. What others should know:With the .20g BBs you'll want to set the hop-up just over half way.
Things I liked:I love the rubber lining in the sling. Holds my gun nicely when I move about. Things I would have changed:Perhaps make the adapters for guns without sling mounts a tad bit bigger, not a problem though. What others should know:Have the rubber lining pointing outward so it will grip. =P
