Particle colliders giving mixed results

I downloaded gun particle effects that i put on my avatar. The collisions affect objects with rigid bodies, however not every phys object in game appears to have rigid bodies. I know there has to be more ways to have particles interact with other objects because i have seen avatars that can do that.

The predator avatars in Sci Fi Avatars world has the ability to blast blocks all over the room, but my avatar has zero affect on them and I need to figure out why that is. Any Ideas??

You can see that the predator can blast objects with no problem, i have witnessed him do this in many different worlds, whereas my avatar has zero power whatsoever on the cubes.

But in Unity its a different story. The box that has rigid bodies immediately reacts to gunfire
