Hi how many rounds have you guys put through a non cromed barrel (not stainless I mean regular barrel) and I am selling my bushmaster m4 upper without bolt it has about 200 round through it because I swiched the upper for a 24"  how much shouls I ask?

I haven't seen Bushmaster sell an M4 upper with a non-lined barrel... you also don't mention whether it's an A2 or A3 upper. So... I can't give you a clue as I don't have any idea what you really have there.

sorry I bought a 24" upper thats not cromed thats why I wanted to know how many rounds it woulkd last.My bushmaster is cromed and I have no use for it becouse I like the longer barrel. My bushmaster is a a3 I dont know if I am going to keep the handel or not plus I was thing about throwing in my bussnell trhopey reddot wich is $89.00 brand new and handel mout. I just cant decide if I would shoot that m4 much now so I will probley sell it

It will take thousands of rounds to wear out any barrel.  Just shoot it and enjoy it.
