Weight of barrels

[cueball]

Hi everyone, i am building an AR for the missus so weight is a consideration. can anyone tell me where to find the weight difference between a 14.5" M4 profile barrel vs a 16" Hbar barrel. barrel only, not complete upper etc.
Thanks

Not sure on actual weights.
But i can tell you that an 11.5" Heavy barrel is heavier than a 14.5" M4 profile just by holding each in my hands.

A 16" is going to be a pig

I don't thing there is any justification to utilize heavy barrels, unless its the availability.

On a short 10.5" ala LMT medium profile is sufficient. 14.5"/16.5" gov profile works well.
