| Is overall barrel length measured from the feed ramp cuts (complete end to end) or from the beginning of the lans and grooves (front of chamber)? |
|
This is best measured with a long cleaning rod... Close the bolt, and put the rod down the bore. Mark the rod where it reaches the muzzle. Measure this... That is barrel length. Keep in mind, any muzzle attachment that is not permanently attached via pin and weld DOES NOT count as barrel length. |
