well it is if you shoot at anyones building then you are raidblocked for 5 mins and this is using my gun.
Pretty daft this as you could keep someone RB for hours if you had the patience.
Even shooting a campfire out in my own building is RBlocking me
What is the option to turn this off 
I only want RB for rocket or c4 damage

from the documentation
damageTypes
List of damage types that will start blocking behavior. Such as: bullet, blunt, stab, slash, explosion, and heat damage.

thanks will check that out
