Initially it was a small line on the magazine tube.
After 400-600 it was like a small smooth dent across my magazine tube.
After another 400-600 it is like a small groove with rough edges.
I snap couple pictures with my phone.
One picture shows wear mark location relative to barrel.
I think the mark is from the steel ring located in the gas system but the ring is smooth.
Is this normal wear or do need to contact Mossberg?
