We'd need a lot more information to answer the question.

Cold hammer forged?
Barrel profile?
Chrome lined?
Melonite treated?
4140/4150 steel?
Rate of fire?

If you're so inclined a good event to look into is why the SOCOM profile M4 barrel was created. There's a lot of good data that has been released about its' development.
