Barrel deep cleaned, polished lightly to touch up and deep cleaned again. Got my tactacam 4.0 the other day and mounted it under the bbl. Looks good, but I think I'm going to end up removing the VPOD mount in lue of a simple shooting stick and move the cam back. The phone APP for it is pretty neat too. You can control almost all the functions of the camera via wifi and get a real time picture of where the gun/cam is pointed and can start and stop recording if someone else is running the gun.
