It shoots well at 300fps on 0.25g bbs. 

It's a specna m249 polymer version. Its missing a rear stock pin, heat shield, top cover (although it does come with a 2 tone metal top cover that is broken). The mag release is also broken but it shoots if you hold an m4 mag in it. The grip is wobbly and the grip cover spring is bent and loose. No box mag. I think that's everything. Please check the photos or ask is you're not sure about anything.
