# They relate to choke type, i.e., full, modified....
If you mean a choke bored barrel, it designates the amount of constriction a shotgun barrel has.
4 notches = cylinder choke (open), and one notch = full choke (tight)
They probably denote what choke the barrel has.
It stands for Modified choke.
Degree of choke
To determine the choke on a Westernfield Model 155A shotgun, you can look for markings on the barrel, which may indicate the choke type (such as "IC" for Improved Cylinder, "M" for Modified, or "F" for Full). If there are no markings, you can perform a choke gauge test using a choke gauge tool or a caliper to measure the constriction at the muzzle. Alternatively, you can pattern the shotgun using different loads and see how the shot spreads to infer the choke type.
