Animation for Direct Impingement vs. Gas Piston AR?

[viras]

I remember someone posting a .gif image/flash animation which was an animation of how the Direct Impingement Gas Operation system works on an AR. It was pretty cool, however I cannot find it now. Any help?

Also, does anyone have any similar animations on how the Gas Piston AR's work?

Thanks in advance!

Update: Found the DI animation. My Google Kung-Fu is STRONG!

Here's an animation comparing the hk416 to an m4.

Probably the best animation I've seen so far.

Very nice animation from Bushmaster and also identifying the parts name. Cool.

Thanks Booshanky - that's awesome!

If anyone else has any more animations like this, please post them!

Some people learn visually, while some learn by hands-on experience, while others learn by reading. I'm a very visual person and stuff like this really help me understand how it all works.
