Things I liked:The weight,feel and look are great (now that I replaced the co2 cylinder retention knob) see "Things I would change..." Things I would have changed:I changed the co2 cyl. ret. knob to a allen set screw. Removed the plasic knob(now trash can) cut off the threaded portion & replaced it with a short allenhead set screw. What others should know:if you purchase this gun, you WILL have a lot of FUN. Be safe!
