This is a great gun. It fires at 350 FPS has Auto and semi auto its a real nice replica. Fully ajustible sights, scope,& stock. I weighs about as much as a real 1. has a decent rate of fire. all metal gearbox plastic body tight boar barrel. Over this is a good gun i rate it.

Four stars ****

My team bought color=#BF0040][/color][/color]me this really nice M4 mostly metal. Got it off ebay and it was made by A&K After i got it it shot well but for some reason after shooting it on semi-auto for a few times it woundnt shoot and i had to switch it to safety and back to get it to work. But it got better (i assumed it was the battery) but a month later :evil:  i was shooting it in bursts on auto and suddenly it wouldnt fire the charge was going to the firing mechanism but it wouldnt fire :cry:  i tryed everything. Can somone shed some light on this. (P.S. when i had this shipped they just wrapped paper arounds the guns box and shipped it and when i got it a corner of it was dented in i think that might have somthing to do with it)
