If the muzzle is recessed, make sure you’re measuring to the top of the muzzle recess, not the barrel’s floor. If the muzzle is flush, make sure the measuring rod is flush with the muzzle when it makes contact with the bolt face.
Some barrels are threaded on the muzzle for the attachment of muzzle gadgets or suppressors. In such circumstances, the measurement is often taken from the bolt face to the top of the threaded portion, which can seemingly be an extra step in your measurement. Pay attention to this if you wish to measure to the muzzle itself and never embody the thread.
Upon getting taken the measurement, document it precisely. Notice the measurement in inches or millimeters, together with the measuring unit. Make sure you doc the measurement and any particular particulars concerning the barrel for future reference.
Particular Issues for Correct Measurement
Various factors can have an effect on the measurement, so it’s essential to contemplate these parts for accuracy.
The form of the chamber can have an effect on how the measuring rod interacts with the bolt face. Make sure the rod is making full contact.
