Here is a quick look at an engraved Minicocker barrel. This stock short bull barrel came from Tyler / Socalpumpballer on mcb/instagram.
This style green autococker thread barrel was the default stock barrel for most of the earliest Minicockers (probably 92/93?). This example was engraved will be going on an early Minicocker body engraved for the Florida Bushmasters.
The engraving reads.
