A block to stop weapons

[HerrColonel]

This idea my be difficult for me to explain. I would like to have a block that cannot be passed through by bullets fired from the entity they're putted on.

For example, I have a "evil button" in my office, killing everyone in front of me with a wave of bullets, fired by logic. But the bullets are dangerous for everything around the base. With this block I could build a wall to stop the bullets.

I'm fairly sure you can build small wall-ships to rail-dock in the office; since they're docked separate entities, they should stop the bullets.
