Mossberg 500c 20ga 18.5" Security Barrel

[Ronald]

I'm looking to make my Mossy 500c 20 gauge a little more HD friendly, so if you've got a new or used 18.5" security barrel that you'd like to part with, please let me know. Thank you

I've read other threads suggest contacting Mossberg directly, since these seem to be difficult to find in the wild.
