Dims of C8A2 barrel

[CanAm]

Does anyone have the basic dimension of a Diemaco C8A2 lightweight barrel?

Even just the minimum diameter?

 

[8 ball]

My literature says .570" forward of the gas block.

Thanks

What about under the handguard? Does it taper like the M16A1, or it is .570 as well?

Kind of, barrel is .750 at the FSB instead of .625, but otherwise very similar. The taper at the muzzle is a larger diameter than is possible with the M16
