FS: Airsoft gun. Fully auto M4

This isnt the gun. and 500 per second was what i copied from it’s specs. It does shoot hella fast though.

500 per sec would be taking 500 bbs in your Andre the Giant-sized hands and throwing them all at once. Does this shoot that fast?

hmmmmmm. i might want another one for another gun. me or my brother might want o pick this up. i have an m16a4 with a red dot. its nice but its the sniper package so its long/heavy. you got a pic?
