Things I liked:Looks and feels like a real firearm. The blow back is realistic. Shoots smooth and fast. Easy to load and easy to reload the magazine. Things I would have changed:The lever for the CO2 is not pleasing to the eye. The hammer should be able to release for better safety. The blow back makes shooting accurate at farther distances more difficult. What others should know:When first using the gun with a brand new CO2 cartridge it shoots powerful but after a few shots the air compression goes down a lot. You have to let it rest a few minutes to gain back its strength.
