Cheapest USA made AR barrel?

Is there a way to get an USA-made AR barrel for $50? I. Have never used the same barrel twice in the last 3 years, so I'd like to keep it cheap. 16" M4 profile, 5.56, 1:7 will do. I've used the Anderson barrels a couple of times. <br><br>Can't seem to find any cheap USA-made ammo, but 5.56 is getting cheaper. Check that out if you haven't noticed.
