Full Metal GBB WE M9. This gun shoots hard. It chronoed at 330 fps when I received it. This gun also shoots very consistant at close range. I did have a slight problem when I was shooting at longer ranges though. At a range over 30 feet the bb's path would go almost staight up. This was a hopup problem and was quickly fixed. All in all this is a nice weapon that shoots hard and has good accuracy and consistancy.
Gas blow back
High FPS (330)
Inner and outer barrel rattles a little.
Hopup was way off, but was easily fixed.
Pulling the trigger with the hammer back and safety on will sometimes still fire.
