And here's both the business ends of the Judicator Enforcer.

First off I'm aware that the top barrel is too large for assault rifle calibers, resizing it and making the parts of the muzzle break reconnect with the inner tube is a pain in the butt, so looking into sabot, or whatever those spike looking things are, ammunition. They are naturally armor piercing, so it might benefit the Judicator Enforcer.
