This was my fourth gun and it is great. It says it shoots 400 FPS, but I measured it and it really shoots 460 FPS with golden ball bio tac .20 gram bbs. It has has only jammed once but that is because my brother didn't know how to use it. Buy a smart charger for this gun. It takes 12 hours with the charger it comes with but only one hour with a smart charger. This gun's body is Palmer plastic and metal it is really sturdy. It has a metal gear box. It comes with a 600 round magazine. On airsoft megastore it costs $119.00 and ships fast. They have great costumer service and are really nice. This gun is really fun to shoot and I give it 5 out of 5.
